Thank you for your reply.
All I am given is:
The potential on a non-conducting sphere or radius a is given by
V = V0(cos2\theta +cos\theta-1)
And with that I should be able to find the potential and electric fields inside and outside the sphere and the surface charge density?
Given the equation for the potential "on" a non conducting sphere how can the potential and electric field inside the sphere be calculated?
If there is a potential on the sphere am I to assume that there must therefore be a charge build up in the sphere? Is this just calculated by the Laplace...
