Homework Statement
The plane with surface charge sigma lies in x-z plane at y=0, parallel to it at y=a there is a grounded plane. What is the field just above the bottom plane, find the potential between the planes
Homework Equations
discontinuity E=sigma/epsilon, V=Qd/Aepsilon take the gradient I can find V, what is E
The Attempt at a Solution
I know that for an infinite plane just above or below the E field is sigma over epsilon naught. The sigma in this question on the top plane is sigmacos(lambdax) so it depends on x, is sinusoidal. is E sigma/epsilon and i just plug in the sigma given? Or do i do the method of images
