There's a charge, not at the center of a grounded cube. Find the potential in the cube.
The Attempt at a Solution
I'm really just looking for a place to start. I should end up with some kind of series, but I don't know if I should be doing some Method of Images, or Greens Function, or Poisson Equation. The only information I can find is for Laplace's Eqn which doesn't apply here, so I'm kinda stuck.
Just trying to get a head start on some homework, so can someone just point me in the right direction?
