Thanks for the quick reply and good suggestions, weejee. My professor likes to watch us squirm, so I'm not surprised that the solution to this problem will probably require knowledge outside of our course. I'll definitely try the potential to field method first, though. Good thinking.
Homework Statement
I need to find the equation for the electric field intensity \vec{E}(\vec{R}) of a uniformly-charged disk lying in the xy-plane with radius \rho_{0} and surface charge density \rho_{s}' at any point.
Homework Equations
I know that a charged disk doesn't have the symmetry...
