Question:

The dimensions of $\left(\mu_0 \varepsilon_0\right)^{-1 / 2}$ are:

Options:

$\left[L^{1 / 2} T^{-1 / 2}\right]$

$\left[L^{-1} T\right]$

$\left[L T^{-1}\right]$

$\left[L^{-1 / 2} T^{1 / 2}\right]$

Correct Answer:

$\left[L T^{-1}\right]$

Explanation:

$\frac{1}{\sqrt{\mu_0 \epsilon_0}}$ = c (speed of light) and dimensions of c are [LT-1].
