The initial charges on three identical metal spheres are the following: sphere A, +Q; sphere B, – Q/3; sphere C, +Q/3, where Q = 4.0 × 10–11 C. Spheres A and B are fixed in place, with a center-to-center separation of d = 0.8 meters, which is much larger than the spheres. Sphere C is touched first to sphere A, then to sphere B, and is then removed. What then is the magnitude of the electrostatic force between spheres A...
