When a charge is placed on a metal sphere, it ends up, in equilibrium, distributed uniformly over the outer sutface. Use this information to determine the electric field of 3.5uC charge pur on a 4-cm radius aluminum spherical ball ar the following two points in space: 1) a point 3 cm from the center of the ball (an inside point): the magnitude of the electric feld is 2) a point 13 cm from the center of the ball (an outside point): the magnitude of the electric field is
