Question:

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

Options:

$\frac{q^2}{4\pi \epsilon_0 R}$

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

$\frac{3}{5}\frac{q^2}{4\pi \epsilon_0 R}$

None of these

Correct Answer:

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

Explanation:

$\text{ Energy of a uniformly charged solid sphere having charge q and radius R is } $

$U = \frac{3}{5}\frac{q^2}{4\pi \epsilon_0 R}$
