A) Momentum and force
B) Surface tension and surface energy
C) Pressure and Youngs coefficient
D) Momentum of force and angular momentum
Correct Answer: C
Solution :
Pressure \[=\frac{force}{area}=\frac{[ML{{T}^{-2}}]}{[{{L}^{2}}]}\] \[[{{M}^{1}}{{L}^{-1}}{{T}^{-2}}]\] Youngs coefficient \[=\frac{F.l}{A.\,\Delta l}\] \[=\frac{[ML{{T}^{-2}}][L]}{[{{L}^{2}}]\,[L]}\] \[=[{{M}^{1}}{{L}^{-1}}{{T}^{-2}}]\] \[\therefore \]pressure and Youngs coefficient have same dimensions.
