## Homework Statement

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.)

## Homework Equations

since the metal is grounded then only negative charges are left on the surface.

V(r)=[tex]\frac{1}{4\pi\epsilon}[/tex][tex]\sum\frac{q}{r}[/tex]

## 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?
