Two equal charges placed in air separated by a distance 3m repel each other with a force of 0.1 gf. Calculate the magnitude of either of the charges?

Two point charges q_1 and q_2 are separated by a distance r in space:-What happens to the force between the charges:-When the magnitude of the point charge Increases.

Two point charges q_1 and q_2 are separated by a distance r in space What happens to the force between the charges, i) When the magnitude of one of the point charges is doubled. ii) When the distance of separation is halved.

Two equal and opposite charge +q and -q are separated by a small distance 2a. Br Name this arrangement.

Two charges Q and q are placed at a distance ‘d’ from each other. If the magnitude of each charge is doubled and the distance between them halved, the force becomes?

Two point charges q_1 and q_2 are sepa-rated by a distance r in space:- What happens to the force between the charges:- When the distance of separation is decreased. Hence establish the law governing it.

Two charges +3muC and -3muC are separated by a very small distance of 5mm. Br What is the name of the above arrangement?
