5. Since the charge is uniformly distributed throughout a sphere, the electric field 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 field is EqR=402πεwhere qis the magnitude of the total charge and Ris the sphere radius. (a) The magnitude of the total charge is
