Which statement correctly describes the charge distribution and the electric field in the vicinity of a negatively charged spherical conducting shell? A. Charges are uniformly distributed over the outer surface. There will be zero electric field inside the conductor, while just outside the conductor the electric field will be perpendicular to the surface and point inward. B. Charges are uniformly distributed over the outer surface. There will be zero electric field inside the conductor, while just outside the conductor the electric field will be perpendicular to the surface and point outward. C. Charges are uniformly distributed over the outer surface. Both inside and just outside the conductor the electric field points radially inward. D. Charges are uniformly distributed over the inner surface. Both inside and just outside the conductor the electric field points radially inward
