Homework Statement
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
Homework Equations
I believe Gauss Law could be used: Flux = Qin/ε.
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?
