Can only dissimilar charges produce static electricity

It's a strange way of asking you.

When the object is close to the electrostatic object, due to the same charge repulsion and or dissimilar charge attraction, the internal charge distribution of the object changes, so that the electric field is generated between the charged body, until the reverse electric field strength inside the object is just offset with the electric field of the original charged body, and the whole system reaches electrostatic equilibrium, and the internal charge of the object no longer moves directionally.

Summary. Because metal ions are immobile. Movement is only electron.

You have to figure this out. Positively charged because the free electron goes to the other side. Otherwise, metal is not metal.

The ionic clusters inside the solution may move. Static electricity can be generated on the surface of the insulator. Free electrons can be tied up.

The dissimilar charges attract each other, but they are pulled apart by the external electric field and are in equilibrium.

Regarding electrostatic induction, why there is an equal amount of dissimilar charge at both ends, and I understand why it is an equal amount.

Because metal ions are immobile. Movement is only electron. You have to figure this out.

It is positively charged because the free electron runs on the other side. Otherwise, metal is not metal. The ionic clusters inside the solution may move.

Static electricity can be generated on the surface of the insulator. Free electrons can be tied up. The xenoelectric charges will attract each other, but they are in equilibrium when they are pulled apart by external electricity.

This diagram, why is the electric field strength zero inside.

The electric grinding skillful field strength stocking contains 0, that is, the electric charge is not stressed at this point, it may be that there is no electric field source, or it may be shielded, or it may be offset by an electric field of equal magnitude and opposite direction. The direction of the electric field strength is the same as the direction of the electric field lines or the direction of the force of the modified positive charge, and when the electric field strength is zero, the direction is arbitrary, a bit like a zero vector.

So here's the electrostatic shielding, right, why is there an electrostatic shielding.

The positive charge in the rotten spike of the object gathers in the direction of the electric field, and the negative charge gathers in the opposite direction of the electric field, and the two sets of positive and negative charges together will also produce his own electric field, which is directed by the positive charge to the negative starvation charge, which is the opposite of the external electric field, and will synthesize the external electric field.

However, the electric field received by different positions inside is different, and the internal electric field is a uniform electric field.

Why don't you ignore people<>

The electric field lines are curved and the direction of the electric field is different. Definition: In a certain area, the electric field is a uniform electric field with equal strength and the same direction.

When they carry an equal amount of dissimilar charge, the positive and negative charges happen to cancel out completely, and neither is charged. When they carry an unequal amount of dissimilar charge, the remaining charge after the positive and negative charges cancel out is equally distributed between the two, and they have an equal amount of the same charge.

A has 5 positive charges, B has 9 negative charges, and there are 4 negative charges left after contact, and A and B each have 2 negative charges.

What electricity is carried after contact, you just add up their electricity, and if it is negative, it will be negative, and if it is positive, it will be positive.

Two dissimilarly charged conductors come into contact, neutralizing first, and redistributing the remainder. Both must have the same kind of charge.

<> in reality, the electric field lines must not intersect each other.

In order to visually describe the distribution of the electric field, the electric field lines introduce some imaginary curves into the electric field. The tangent direction of each point on the curve is consistent with the direction of the electric field strength at that point; The field strength is strong where the curve is dense, and the field strength is weak where the curve is sparse.

In order to vividly describe the distribution of field strength, some directional curves are artificially drawn in the electric field, and the tangent direction of a point on the curve indicates the direction of the field strength at the point, and the density of the electric field line is directly proportional to the field strength at the point.

The electric field is a substance, and the electric field line is not an objectively existing substance, which was first introduced and used by Faraday. It is an aid to artificially draw an image to describe the distribution of electric fields

Properties: In any electric field, the field strength of each point p has a certain direction. Based on this, we can draw a series of curves in the electric field, so that the tangent direction of each point on the curve is consistent with the direction of the field cover strength of that point, and these lines are called electric field lines.

In space without electric charge, the electric field lines have the characteristics of not intersecting and not interrupting The electric field lines of the electrostatic field also have the following properties:

The electric field lines are not closed, starting from a positive charge or infinity and ending at infinity or a negative charge;

The electric field lines are perpendicular to the surface of the conductor;

The electric field lines are perpendicular to the equipotential surface

The electric field lines that induce an electric field have the following characteristics:

The electric field lines are closed curves;

Closed electric field lines surround magnetic inductance lines

The electric field line is marked with an arrow, indicating the positive direction that the tangent of each point on the line should take (i.e., the direction of the field strength of that point). Using electric field lines, the direction of the field strength at each point through which it passes can be determined, and thus the direction of the electric field force on a positive charge placed at that point can be expressed. However, it should be noted that, in general, the electric field lines are not orbits in which the positive charge is moved by the electric field force.

Because the direction of the charge motion (i.e., the direction of velocity) is not necessarily in the direction of the force.

Note: The electric field lines are imaginary: the electric field lines are a cluster of curves drawn by people to describe the distribution of the electric field, although the experiment simulates the shape of the cluster curve, but the experiment does not confirm the real existence of the electric field lines, and the electric field lines are imaginary

In an electrostatic field, the electric field lines are not closed curves, in which the electric field lines start at a positive charge (or muffle infinity) and end at infinity (or negative charge) without forming a closed curve

The tangent direction of each point of the electric field line is the same as the direction of the field strength of that point

The relationship between the density of the electric field lines and the strength of the electric field:

The density of the electric field line is related to the small field strength, the electric field is strong at the dense part of the electric field line, and the electric field is weak at the sparse part of the electric field line

The electric field lines do not intersect, do not tangent, and do not close in space

The electric field lines between the dissimilar charges in the electrostatic field will not intersect.

The local source of the electric field line is an imaginary line that describes the electric field vividly, and the electric field line does not exist objectively.

The direction of the electric field force is the tangential direction along the electric field lines. If two tangent lines intersect, then at the intersection of the curves, two tangents can be made, and the detected charge will be subject to two different directions of the electric field force, and there can be no two directions of the electric field force at a certain point.

So the electric field lines between the dissimilar charges in the electrostatic field will intersect.

a. The same kind of charge repels each other, and the local charge of the different Tong attracts each other, so A is wrong;

b. There are only two kinds of electric charges in nature, positive and negative, so B is correct;

c. The electrostatic phenomenon is a phenomenon caused by the loss of electrons or the acquisition of electrons by the substance, and the atoms are realized from the electrostatic phenomenon as divisible, so c is wrong;

d. Nuclei of different substances.

When two different objects rub against each other, the weak ability to bind electrons will lose electrons and scatter to make positive charges, and the strong ability to bind electrons will get electrons and be negatively charged Therefore, the essence of triboelectric charging is to transfer electrons, not to create a charge, so D is wrong

Therefore, b

The other parts are not electrified. However, there are some differences due to their shape. Macro said:

Needle-like, charged at both ends, and uncharged at the rest. Plates, charged on both sides, no electricity in the middle. Sphere-like, charged on both sides, with no electricity in the middle, but the boundary between electricity and weakness is unclear.

Microscopic theory: It has little to do with the shape, after the charge is attracted or repulsed, it is impossible to gather at one point, and there is still a repulsion force between the charged that is absorbed or repulsed, resulting in the fact that with the increase of the distance from the charge that is actively induced, the induced charge becomes more and more sparse, and even disappears, but from a macroscopic point of view, this area is very small, except for its large sphere, there may be a wider transition zone.

Three basic types of shapes are listed, and the others can be known according to the principle.

After the two charged bodies came into contact, they were ominously charged without knowing that they were charged, indicating that they had the phenomenon of Zhonghong Sum, so the electricity originally carried by the two charged bodies was an equal amount of dissimilar charge

Therefore, choose D

This problem is caused by the electrical properties at both ends of the molecule, take a look at it.

Since the proximity of the negative charged body to the object polarizes the proximal charge and the distal polarizes the same charge, the attraction is greater than the repulsion, and the gravitational force is generated. The principle of positive charge is the same.

The question is as ...... as why gravitational force existsI can only answer you: because of the Coulomb force.

Just to maintain a normal and stable state (i.e., electrically neutral), just like sodium ions are unstable and like to move, chloride ions are unstable and like to move, and only when they are together, they are neutral and reach a stable state.

You can consider the method of counter-evidence. If the same charge attracts each other and the different charges repel each other, then, for example, it is so prescribed only for the convenience of the narrative. If it is stipulated that macroscopic objects are electrically charged, there will be a certainty.
