A charge +q is located at the center of a hollow thick uncharged spherical shell (thickness b-a). Induction will lead to surface charge on the inner and outer surfaces of the spherical shell. What is the surface charge density for the inner and outer surfaces? What is the net charge on the inner surface? On the outer surface? b) Connectign the outer surface to ground will result in a change in the surface charge density for the outer surface. What is the value of sigma b after grounding? c) Use Gauss' Law to find E inside the grounded metal sphere, a
