There are two charges with charge q and mass m

In summary, the conversation discusses two charges with charge q and mass m that are in equilibrium. The diagram shows the forces of gravity and electric force acting on the particle, and it is noted that equilibrium means the net force is zero.

There are two charges with charge q and mass m and they are in equilibrium. Then, in the diagram why is my teacher saying that electrostatic force(F)=mg? Below is diagram.

OK, you've started with a diagram that correctly shows the gravity force and the electric force. It might help to also show any other forces acting on the particle.

What does "equilibrium" mean in terms of the forces?

Equilibrium means net force is zero, right?

Yes. That's right. If you added (head-to-tail) the force vectors acting on the particle, what would the diagram look like?

1. What is the relationship between the charges and masses of the two charges?

The charges and masses of the two charges are independent of each other. This means that one charge may have a larger or smaller mass than the other, and vice versa.

2. How do the two charges interact with each other?

The two charges will exert electrostatic forces on each other, either attracting or repelling each other based on their respective charges. This force is governed by Coulomb's Law.

3. How does the distance between the two charges affect their interaction?

The electrostatic force between two charges is inversely proportional to the square of the distance between them. This means that the closer the charges are, the stronger the force between them will be.

4. How does the magnitude of the charges affect their interaction?

The electrostatic force between two charges is directly proportional to the product of their charges. This means that the greater the magnitude of the charges, the stronger the force between them will be.

5. Can the masses of the two charges affect their electrostatic interaction?

The masses of the two charges do not directly affect their electrostatic interaction. However, the masses do play a role in determining the acceleration of the charges when they are subject to a force.
