Question

A uniformly charged ball of radius a and charge -Q is at the center of a hollow metal shell with inner radius b and outer radius c. The hollow sphere has a net charge +2Q. Part A Determine the electric field strength in the region r ≤ a. Give your answer as a multiple of Q/ε0. Express your answer in terms of some or all of the variables a, b, c, r, and the constant π. Part B Determine the electric field strength in the region a < r < b. Give your answer as a multiple of Q/ε0. Express your answer in terms of some or all of the variables a, b, c, r, and the constant π. Part C Determine the electric field strength in the region b < r < c. Give your answer as a multiple of Q/ε0. Express your answer in terms of some or all of the variables a, b, c, r, and the constant π. Part D Determine the electric field strength in the region c < r. Give your answer as a multiple of Q/ε0.
