A solid nonconducting sphere of radius R carries a charge Q distributed uniformly throughout its volume. At a certain distance r$1($r$1<$ 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 $2$R$,$ the magnitude of the electric field at the same distance r$1$from the center would be equal to

Question $2$ options:

E$/2.$

$8$E$.$
