A spherical cavity of radius a is within a large, grounded conductor. A charge q is placed within the cavity at a distance b from the center. a) Find the potential at all points within the cavity. Use spherical coordinates with origin at the center and z axis passing through q. b) Find the electric field, E vector at all points within the cavity. What is E vector at the center of the cavity
