A) Momentum and force
B) Pressure and surface tension
C) Moment of force and angular momentum
D) Surface tension and surface energy
Correct Answer: D
Solution :
Surface tension \[=\frac{\text{Force}}{\text{Length}}=\frac{[ML{{T}^{-2}}]}{[L]}=[M{{T}^{-2}}]\] Surface energy\[\text{=}\frac{\text{Work}\,\text{done}}{\text{Increase in area}}\] \[=\frac{[M{{L}^{2}}{{T}^{-2}}]}{[{{L}^{2}}]}=[M{{T}^{-2}}]\]
