A small conducting spherical shell with inner radius a and outer radius b is concentric with a larger conducting spherical shell with inner radius c and outer radius d (see the Figure (Figure 1) ). The inner shell has total charge +2q, and the outer shell has charge +4q.
A) Calculate the magnitude of the electric field in terms of q and the distance r from the common center of the two shells for r B) Calculate the magnitude of the electric field in terms of q and the distance r from the common center of the two shells for a C) Calculate the magnitude of the electric field in terms of q and the distance r from the common center of the two shells for b D) Calculate the magnitude of the electric field in terms of q and the distance r from the common center of the two shells for c E) Calculate the magnitude of the electric field in terms of q and the distance r from the common center of the two shells for r>d. Express your answer in terms of the variables q, r, a, b, c, d, and constants ? and ?0.
