Two identical conducting spheres A and B carry equal charge and exert electrostatic forces of magnitude F on each other. 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 becomes: F/2 F/4 3F/8 F/16 0

Identical isolated conducting spheres 1 and 2 have equal charges and are separated by a distance that is large compared with their diameters (see Figure (a)). The magnitude of the electrostatic force acting on sphere 2 due to sphere 1 is F = 8.9 N. Suppose now that a third identical sphere 3, having an insulating handle and initially neutral, is touched first to sphere 1 (see Figure (b)), then to sphere 2 (see Figure (c)), and finally removed (see Figure (d)). What is the magnitude of the electrostatic force F′ that now acts on sphere 2? Number Units

The figure shows four identical conducting spheres that are actually well separated from one another. Sphere W (with an initial charge of zero) is touched to sphere A and then they are separated. Next, sphere W is touched to sphere B (with an initial charge of −26e) and then they are separated. Finally, sphere W is touched to sphere C (with an initial charge of 50e), and then they are separated. The final charge on sphere W is 20e. What multiple of e gives the initial charge on sphere A?
