If energy E, velocity v and time T are chosen as fundamental units, the dimensions of surface tension will be:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → $[Ev^{–2}T^{–2}]$
$Surface\, tension = \frac{force}{length}$
$=\frac{energy}{length × length}=\frac{energy}{(speed \times time)^2}$
$=EV^{–2}T^{–2}$
