\mu_0

and

\varepsilon_0

denote the magnetic permeability and electrical permittivity of free space, then the dimensions of

\frac{1}{\sqrt{\mu_0 \varepsilon_0}}

are similar to

View answer and explanation

Correct option: B

velocity

Option B (velocity) is correct because the dimensions of

\frac{{1}}{{\sqrt{{\mu_0 \varepsilon_0}}}}

are

[LT^{-1}]

, which is the dimension of velocity.
