3. Consider a hollow conducting spherical shell with inner radius a and outer radius b. The magnitude of the electric field at the inner surface r=a is E, which is in the direction toward the center of the sphere and is uniform on the surface. The magnitude of the electric field at the outer surface r=b is E, which points outward and is uniform on the surface. Give your answers in terms of E, E,, a, b, and Ɛo a) What is the surface charge density on the inner surface? b) Determine the total charge inside the cavity. c) Determine the electric field in the region between the points a and b.
