The energy of a uniformly charged solid sphere of total charge q and radius R is

$\frac{q^2}{4\pi \epsilon_0 R}$ $\frac{q^2}{8\pi \epsilon_0 R}$ $\frac{3}{5}\frac{q^2}{4\pi \epsilon_0 R}$ None of these

$\frac{q^2}{8\pi \epsilon_0 R}$

$\text{ Energy of a uniformly charged solid sphere having charge q and radius R is } $ $U = \frac{3}{5}\frac{q^2}{4\pi \epsilon_0 R}$
