Two identical conducting spheres 1 and 2 carry equal amounts of charge and are ficed apart at a certain distance larger than their diameters. The spheres repel each other with an electrical force of 88mN. A thired identical sphere 3, having an insulating handle and initially uncharged, is touched first to sphere 1 and then to sphere 2 and finally removed. Find the force between spheres 1 and 2 as shown if Figure.

Figure shows that a positively charged rod is brought near two ucharged metal spheres A and B clamped on insulated stands and palced in contact with each other. (i) What would happen if the rod is removed before the spheres are separated? (ii) Would the induced charges be equal in magnitude even if the spheres had different sizes or different conductors? (iii) What will happen if the spheres are separated first and then the rod is rmoved far away?
