Question:

If $U_E$ = electric field energy density and $U_m$ = magnetic field energy density. Then,

Options:

$\frac{U_E}{U_m}>1$

$\frac{U_E}{U_m}=1$

$\frac{U_E}{U_m}<1$

$\frac{U_E}{U_m}$ is variable

Correct Answer:

$\frac{U_E}{U_m}=1$

Explanation:

The correct answer is Option (2) → $\frac{U_E}{U_m}=1$ $n^{2}$
