Athick, spherical shell made of solid metal has an inner radius a = 0.18 m and an outer radius b = 0.33 m, and is initially uncharged. a point charge q = 5.00 c is placed at the center of the shell. what is the electric field strength in the region r < a? express your answer in terms of 1/r2. tries 0/8 what is the electric field strength in the region a < r < b? express your answer in terms of 1/r2. tries 0/8 what is the electric field strength in the region b < r? express your answer in terms of 1/r2. tries 0/8 what is the induced charge density at r = a? (in c/m^2) tries 0/8 what is the induced charge density (in c/m2) at r = b? (in c/m^2)
