Concept

Problem: Two identical spheres A and B carry charges Q and 2Q, respectively. They are separated by a distance much larger than their diameters. A third identical conducting sphere C is uncharged. Sphere C is first touched to A, then to B, and finally removed. As a result, the electrostatic force between A and B, which was originally F, becomes: (1) 5F/16 (2) F/4 (3) 3F/8 (4) F/8 (5) 7F/16
