A uniformly charged solid sphere of radius $$R$$ has potential $${V_0}$$ (measured with respect to $$\infty $$) on its surface. For this sphere the equipotential surfaces with potentials $${{3{V_0}} \over 2},\,{{5{V_0}} \over 4},\,{{3{V_0}} \over 4}$$ and $${{{V_0}} \over 4}$$ have radius $${R_1},\,\,{R_2},\,\,{R_3}$$ and $${R_4}$$ respectively. Then

A

$${R_1} = 0$$ and $${R_2} < \left( {{R_4} - {R_3}} \right)$$

B

$$2R < {R_4}$$

C

$${R_1} = 0$$ and $${R_2} > \left( {{R_4} - {R_3}} \right)$$

D

$${R_1} \ne 0$$ and $$\left( {{R_2} - {R_1}} \right) > \left( {{R_4} - {R_3}} \right)$$
