Question
If energy (E), velocity (V) and time (T) are chosen as the fundamental quantities, the dimensional formula of surface tension will be
$\left[ {E{V^{ - 2}}{T^{ - 2}}} \right]$
$\left[ {{E^{ - 2}}{V^{ - 1}}{T^{ - 3}}} \right]$
$\left[ {E{V^{ - 2}}{T^{ - 1}}} \right]$
$\left[ {E{V^{ - 1}}{T^{ - 2}}} \right]$
