Q97 / 200 · NEET 2011 (Screening) · Physics

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

  • A
    $\left[\mathrm{L}^{-1} \mathrm{~T}\right]$
  • Correct answer
    B
    $\left[\mathrm{LT}^{-1}\right]$
  • C
    $\left[\mathrm{L}^{-1 / 2} \mathrm{~T}^{1 / 2}\right]$
  • D
    $\left[\mathrm{L}^{1 / 2} \mathrm{~T}^{-1 / 2}\right]$

Solution

This expression for speed of light and the dimensions of speed of light are $\left[\mathrm{LT}^{-1}\right]$.

Hence, the correct answer is option: 'B'.
