A thin, metallic, spherical shell of radius a = 5.0 cm has a charge qa = 1.00×10^-5 C. Concentric with it is another thin, metallic, spherical shell of radius b = 7.50 cm and charge qb = 3.00×10^-6 C. Find the electric field at radial points r where r = 11.2 cm. Discuss the criterion one would use to determine how the charges are distributed on the inner and outer surface of the shells. What is the charge on the outer surface of the outer shell?
