1. The problem statement, all variables and given/known data Two thick, parallel plates of thickness d and uniform charge densities (Coulombs per unit volume) ρ and −ρ are placed next to each other, as shown in the figure. The negatively charged plate is located between –d and 0 on the x-axis and the positively charged plate between 0 and d on the x-axis. The z-axis points out of the page. Assume that both plates are infinite in y and z. Find the expressions for the x-, y-, and zcomponents of the electric field E(x) as a function of the x-coordinate. Write your solution in terms of ε0, not ke. Is the net force per unit area between the plates: attractive, repulsive or zero. Setup the integral to compute the pressure on the plates 2. Relevant equations I believe Gauss Law could be used: Flux = Qin/ε. 3. The attempt at a solution I would imagine a cylinder crossing the 2 plates and measure the field on each surface: they are going to be in the same direction, I think. The problem is that I cannot fully imagine the situation: Is the field w on the left and equal to the sum on the right?
