Question Details:

The figure shows a solid metal sphere at the center of a hollow metal sphere.

1- What is the total charge on the exterior of the inner sphere?

2- What is the total charge on the inside surface of the hollow sphere?

3- What is the total charge on the exterior surface of the hollow sphere?

These problems seem easy, but I just can't figure them out. No similar examples are found in my book. Any help is much appreciated!

This is what I've done:

Create an imaginary Gaussian sphere of radius 8cm so that it passes through the point where E is 15000N/C.

The flux should equal to (-15000)(4pi0.08^2) = q/(8.85x10^-12) the answer i get is wrong!
