A thick spherical shell of inner radius A and outer radius B has a charge of magnitude +2*Q spread throughout its volume according to the equation:

( r ) = 3r+5r6

There is also a point charge of magnitude -Q in the exact middle of the sphere.

Use Gauss' Law to determine the electric field in the following regions:

A) (12 points) r < A

B) (12 points) A < r < B

C) (12 points) r > B (you may assume the gaussian surface is far enough away so that

it encloses all of the charge in the system).
