Question $9(1$ point$)$

A solid nonconducting sphere of radius $R$ carries a uniform charge density throughout its volume. At a radial distance $r_1=\frac{R}{4}$ from the center, the electric field has a magnitude $E_0.$ What is the magnitude of the electric field at a radial distance $r_2=2R?$

E$0/2$

E$0/4$

$E_0$

$2E_0$

zero
