This looks like a test preparation homework problem, but it is different!

An insulating spherical shell has an inner radius b and outer radius c. The shell has a uniformly distributed total charge +Q. Concentric with the shell is a solid conducting sphere of total charge +2Q and radius a<b. Find the magnitude of the electric field for r<a.
