Point charge between parallel conducting planes. A charge is placed between two infinite planes as in Figure 5.40.
(a) Show the location and magnitude of the first few image charges.
(b) Place a system of coordinates so that the left plate is at x = 0 and the point charge is at (x = 3d/4, y = 0) and calculate the potential at the middle point between the plates (x = d/2, y = 0) using the first six image charges (plus the original point charge).
