Suppose a point dipole is located at the centre of a grounded spherical conducting shell. Find the potential and electric field at points inside the shell. (Hint: Use zonal harmonics that are regular at the origin to satisfy the boundary conditions on the shell.)
since the metal is grounded then only negative charges are left on the surface.
The Attempt at a Solution
i'm not sure the effect of spherical shell on the potential at any points inside the points, anyone can offer some insight thanks?
