Question

Extra credit As shown in Fig. 2, two parallel plates are connected by a wire so that they remain at the same potential. Let one plate coincide with the yz plane and the other with the plane s (see diagram). The distance s between the plates is much smaller than the lateral dimension of the plates. A point charge Q is located between the plates at -b. What is the magnitude of the total surface charge density on the inner surface of each plate? (Extended hint:) The total surface charge on the inner surface of both plates must of course be -Q (why?), and we can guess that a larger fraction of it will be found on the near plate. If the charge were very close to the left plate, b < s, the presence of the plate on the right couldn't make much dfference. However, we want to know exactly how the charge
