10. A shell of solid metal sphere of outer radius Ro = 2m and inner radius of R1 = 1m has a charge of Q1 = 4C placed on it. After the charge is placed on the sphere, a charge of Q2 = 6C is then placed at the center of the sphere. Find the electric field everywhere in the sphere. What are the charges on the inside of the sphere, and outside the sphere.
