Two charge spheres separated at a distance d exert a force F on each other. If they are immersed in a liquid of dielectric constant K=2, then the force (if all conditions are same) is

A charge Q exerts a 12 N force on another charge q. If the distance between the charges is doubled, what is the magnitude of the force exerted on Q by q?

Two particles having charge Q_(1) and Q_(2) , when kept at a certain distance exert a force F on each other . If the distance between the two particles is reduced to half and the charge on each particle is doubled , the force between the particles would be

How is force between two charges affected when each charge is doubled and distance between them is also doubled?

When the distance between two charged particles is doubled, the force between them becomes

When the distance between two charged particles is doubled, the force between them becomes:
