1. The problem statement, all variables and given/known data Two plates of equal area: length b, width w On one side, the plates are a distance d away from each other, on the other side, a distance d+a 2. Relevant equations No equations given. Using E= kq/r^2, V=-∫E*dl 3. The attempt at a solution E = kq ∫∫dxdz/(x^2 + z^2 + y(x)^2) y(x) = a + ax/b Integrating x from 0 to b, and z from 0 to w. Doing this gives a very very messy solution, give me the impression that this is the incorrect path.
