If momentum $(P),$ area $(A)$ and time $(T)$ are taken to be the fundamental quantities then the dimensional formula for energy is :
$\left[ PA ^{-1} T ^{-2}\right]$
$\left[ PA ^{1 / 2} T ^{-1}\right]$
$\left[ P ^{2} AT ^{-2}\right]$
$\left[ P ^{1 / 2} AT ^{-1}\right]$
In terms of resistance $R$ and time $T$, the dimensions of ratio $\frac{\mu } {\varepsilon }$ of the permeability $\mu $ and permittivity $\varepsilon $ is
If the dimensions of a physical quantity are given by $M^aL^bT^c$ ,then physical quantity will be
Dimensions of kinetic energy are
Using dimensional analysis, the resistivity in terms of fundamental constants $h, m_{e}, c, e, \varepsilon_{0}$ can be expressed as
