Homework Equations

The Attempt at a Solution

You use spherical coordinates, but without boundary conditions, you will not be able to find the potential, so you need to specify them.

Barring time-dependent boundary conditions, "conducting" means that the entire sphere is an equipotential.

So, my solution will satisfy:

$$\nabla^{2}\Psi = 0$$

$$\Psi = \sum a \Psi$$

Should I assume there will be no potential outside the spheroid (or whatever)? And do the boundary conditions determine what particular solution (there is a table of different ones) it will be?

I am not sure exactly what you are looking for. Check this reference. It is pretty good and comes with examples.
