N My Notes When a charge is placed on a metal sphere, it ends up in equilibrium at the outer surface. Use this information to determine the electric field (in N/C) of -2.0 pC charge put on a 9.0 cm radius aluminum spherical ball at the following two points in space. (Enter the radial component of the electric field.) (a) a point 3 cm from the center of the ball (an inside point) N/c)f (b) a point 15 cm from the center of the ball (an outside point) -8e+06 %3D Additional Materials eBook m.
