Problem
Two identical conducting spheres A and B carry equal charge. They are separated by a distance much larger than their diameter, and the force between them is F. A third identical conducting sphere, C, is uncharged. Sphere C is first touched to A, then to B, and then removed. As a result, the force between A and B would be equal to
(1) 43F
(2) 2F
(3) F
(4) 83F
