A solid nonconducting sphere of radius R carries a charge Q distributed uniformly throughout its volume.At a certain distance r1 (r1 < R) from the center of the sphere,the electric field has magnitude E.If the same charge Q were distributed uniformly throughout a sphere of radius 2R,the magnitude of the electric field at the same distance r1 from the center would be equal to
