- | Outside the ball, the electric field exists as if the ball were a point charge! | + | Outside the ball, the electric field exists as if the ball were a point charge! It is also important to note that the relationships seen in our above equations also agree with what we already know about insulating spheres of charge. |

We repeat the process above for the case that the ball is a conductor. Notice that much of the reasoning is the exact same. We still have spherical symmetry, and we choose the same Gaussian surface. It is pictured below for both $r<R$ and $r>R$. | We repeat the process above for the case that the ball is a conductor. Notice that much of the reasoning is the exact same.
