MCQ
Dimension of $\frac{1}{\mu_0 \varepsilon_0}$ should be equal to
  • A
    $T ^2 / L ^2$
  • B
    $L / T$
  • ✓
    $L ^2 / T ^2$
  • D
    $T / L$
✓

Answer

Correct option: C.
$L ^2 / T ^2$
c
$\frac{1}{\mu_0 \in_0}=c^2 \Rightarrow\left[\frac{1}{\mu_0 \in_0}\right]=\left[ c ^2\right]=\left[ L ^2 T ^{-2}\right]$
