A Charged Spherical Shell and a Point Charge.

A spherical conducting shell of radius 1.21 [m], carries charge 4.10×10-6 [C], distributed uniformly over its surface. At the center of the shell there is a point charge 3.90×10-9 [C].

Let Pi and Po be points inside and outside the spherical shell, respectively. The distance of Pi from the point charge is 1.06 [m], whereas is Po is 5.27 [m] away from the point charge.

Calculate the electrostatic potential at a Pi and Po.

The electrostatic inside the shell (at a Pi) is?

The electrostatic outside the shell (at a Po) is ?
