Q. The unit of expression $\mu_{0}\varepsilon_{0}$ are
A) $ms^{- 1}$
B) $m^{2}s^{- 2}$
C) $s^{2}m^{- 2}$
D) $sm^{- 1}$
Explanation
(c) Velocity of light, $c = \frac{1}{\sqrt{\mu_{0}\varepsilon_{0}}}$
or $\mu_{0}\varepsilon_{0} = \frac{1}{c^{2}} = \frac{1}{\left( ms^{- 1} \right)^{2}} = s^{2}m^{- 2}$
