Question: I have a thick spherical shell (inner radius a and outer b) with charge density = kr^2. I need to find the field and potential at all points in space and calculate the energy.
Is it possible to take the equation for the electric field of a solid sphere, and integrate from a to b? Or should I find a way to relate the volume charge density to a surface charge density and then integrate the equation for the field of a thin hollow sphere over the radii of various shells?
Any advice would be appreciated...
Cheers,
