Applications of Dimensional Analysis

If energy (E), velocity (V) and time (T) are chosen as the fundamental quantities, the dimensional formula of surface tension will be

Show answer and solution

Answer: (a)

Surface tension = energy/area $= E/L^2$ .
Length $L = VT$ , so $L^2 = V^2T^2$ .
Surface tension $= [EV^{-2}T^{-2}]$ .
So the answer is (a).
