Problem 18.14 Two very large metal parallel plates are 15.0 cm apart and carry equal, but opposite, surface charge densities. (Figure 1) shows a graph of the potential, relative to the negative plate, as a function of z. For this case, is the distance from the inner surface of the negative plate, measured perpendicular to the plates, and points from the negative plate toward the positive plate.
