Insulating spherical shell prob

SUMMARY

The discussion focuses on calculating the electric field magnitude within the region of a small insulating spherical shell with inner radius a and outer radius b, which is concentric with a larger insulating spherical shell. The inner shell carries a total charge of +q, while the outer shell has a charge of -q. The formula proposed for the electric field in the region where radius is less than b is q/(4*pi*Epsilon 0*(b-a)^2). The expectation of a constant electric field in this intermediate region is also questioned.

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 formula be correct?

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

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