Homework Help: Insulating spherical shell prob!

  1. Oct 24, 2005 #1
    A small, insulating, spherical shell with inner radius a and outer radius b is concentric with a larger insulating spherical shell with inner radius c and outer radius d. The inner shell has total charge +q distributed uniformly over its volume, and the outer shell has charge -q distributed uniformly over its volume.

    How would i calculate the magnitude of the electric field for a < radius < b?

    Would this forumla be correct?

    q/(4*pi*Epsilon 0*(b-a)^2)

    Why would you expect the electric field to be constant in the intermediate region?
