In two cases, two identical conducting sphere are given equal charges, in one case of the same type whereas in another case of opposite type. The distance between the spheres is not large comparing with the diameter. Let `F_(1)` and `F_(2)` be the magnitudes of the force of interaction between the spheres, as shown, then

Two conducting spheres of radii R each are given equal charges +Q and are kept such that their centre are at distance r (geR) . The force of attraction (F) between them is:

Two conducting spheres carry equal charges. the distance between the spheres cannot be considered large in comparison with the diameters of the spheres. In which case will the force of interaction between the spheres be greater (in absolute value): when they carry like charges (Figure (a)) or when they carry unlike charges (Figure (b))?

Force between two identical spheres charged with same charge is F. If 50% charge of one sphere is transferred to the other sphere then the new force will be :-

Two equally charged, indentical metal spheres A and B repel each other with a force F" . The spheres are kept fixed with a distance r between them. A third identical, but uncharged sphere C is brought in contact with A and The magnitude of the net electric force on C is

Two equally charged, indentical metal spheres A and B repel each other with a force F" . The spheres are kept fixed with a distance r between them. A third identical, but uncharged sphere C is brought in contact with A and removed. The magnitude of the net electric force on A is
