7. Since the charge is uniformly distributed throughout a sphere, the electric Feld at the surface is exactly the same as it would be if the charge were all at the center. That is, the magnitude of the Feld is E = q 4 πε 0 R 2 where q is the magnitude of the total charge and R is the sphere radius. The magnitude of the total
