In terms of basic units of mass $(M)$, length $(L)$, time $(T)$ and charge $(Q)$, the dimensions of magnetic permeability of vacuum $\left(\mu_0\right)$ would be
$\left[ MLQ ^{-2}\right]$
$\left[ LT ^{-1} Q ^{-1}\right]$
$\left[ ML ^2 T ^{-1} Q ^{-2}\right]$
$\left[ LTQ ^{-1}\right]$
The dimension of $\frac{\mathrm{B}^{2}}{2 \mu_{0}}$, where $\mathrm{B}$ is magnetic field and $\mu_{0}$ is the magnetic permeability of vacuum, is
The foundations of dimensional analysis were laid down by
Position of a body with acceleration '$a$' is given by $x = K{a^m}{t^n},$ here $t$ is time. Find dimension of $m$ and $n$.
