A We saw in Figure 23.16 that a neutral metal can was attracted to a positively charged glass rod because the rod polarized the can. Lets model this situation in a very rough sense. Suppose a charged sphere C is held near two other charged spheres A and B as shown in Figure P23.62. Lets call the magnitude of the electrostatic force exerted by sphere C on A FA and that on B FB. Derive an expression for the ratio FA/FB. Comment on why a neutral conductor is attracted to a charged object. Figure P23.62
