Question

Homework Problem 5.12 Two thin spherical shells of charge of radius a and d have surface charge densities oa and od. The shells are drawn as the dark circles in

the diagram. The total charge of the inner shell is Qa = +Q and the total charge of the outer shell is Qd = -Q. A neutral spherical conductor is located between the two shells (drawn in gray) and has inner radius b and outer radius c. (a)Draw the electric field map using 4 lines per Q and the induced charge. (b)Compute the electric field everywhere. (c)Compute the potential difference between the outer shell at radius d and the inner shell at radius a, AVda (d)Compute the total charge on the inner surface of the conductor.
