A charge of −24 μC is distributed uniformly throughout a spherical volume of radius 14.0 cm. Determine the electric field (in N/C) due to this charge at the following distances from the center of the sphere. (Enter the radial component of the electric field.) (a) 3.0 cm E→ = (N/C)r^ (b) 8.0 cm E→ = (N/C)r^ (c) 30.0 cm E→ = (N/C)r^
