Two spherical conductors B and C having equal radii and carrying equal charges in them repel each other with a force F when kept apart at some distance. A third spherical conductor having same radius as that of B but uncharged is brought in contact with B, then brought in contact with C and finally removed away from both. The new force of repulsion between B and C is

A third spherical conductor having same radius as that B but uncharged is brought in contact with B, then brought in contact with C and finally removed away from both. The new force of repulsion between B and C is

Two spherical conductors A and B, having equal radii and carrying equal charges on them, repel each other with a force F when kept apart at some distance. A third spherical uncharged conductor C having the same radius is brought in contact with A. It is then detached from A and brought in contact with B and finally removed away form both. What is the new force of repulsion between A and B?
