Quiz 4 -- Gauss's Law

A solid nonconductive spherical ball of diameter 1.0 cm is uniformly charged such that is has an electric field of 20 kV/m at its surface.

[ball of charge]

1. How much charge is on the ball?

2. What is the magnitude of the electric field halfway to the center of the ball?

Now:
3. If the ball were made of a conductive material, how would the answers to 1) and 2) change?
