24. Two identical conducting spheres, A and B, carry equal charge. They are initially separated by a distance much larger than their diameters, and the force between them is F. A third identical conducting spheres, 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 is equal to
(A) 0
(B) F/16
(C) F/4
(D) 3F/8
(E) F/2
