Question

Two very large metal parallel plates are 20.0cm  apart and carry equal, but opposite, surface charge densities. the figure(Figure 1) shows a graph of the potential, relative to the negative plate, as a function of x. For this case, x 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.

Explanation / Answer

E = dV/dx = 5/.2 = 25 V/m
