Force of attraction between two point electric charges placed at a distance d in a medium is F . What distance apart should these be kept in the same medium, so that force between them becomes F//3 ?

Force of attraction between two point charges placed at a distance 'd' is F. What distance apart should they be kept in the same medium, so that the force between them is 2F ?

Force of attractio between two point electric charges placed at a distance .d. in a medium is F. What distance apart should these be kept in the same medium, so that between them beComes F//3

The Coulomb's repulsive force between two point charges placed at distance d apart, is F. If the distance is increased to 2d then the repulsive force between the charges as compared to its previous value, will become A. 1//4 the previous distance B. 1//2 C. 3//4 D. same
