Physics Problem: Gauss' Law and Finding the Electric Field in Concentric Spheres

Physics in 24 Problems. I'm picking 24 HW problems from Fundamentals of Physics (Halliday Resnick and Walker) and solving them as a way of teaching the content.

problem 49
In Fig 23-50, a solid sphere of radius a = 2.00 cm is concentric with a spherical conducting shell of inner radius b = 2.00a and outer radius of c = 2.40a. The sphere has a net uniform charge q1 = 5.00 fC; the shell has a net charge of q2 = -q1. What is the magnitude of the electric field at different values for r?

I've always found this to be such a fascinating concept!
