The pair of physical quantities not having the same dimensions is
Answer: (B) Surface tension and impulse
- Pressure and Young's modulus: both $[ML^{-1}T^{-2}]$.
- Surface tension (force per length) $[MT^{-2}]$; impulse (force × time) $[MLT^{-1}]$: different.
- Torque and energy: both $[ML^2T^{-2}]$.
- Angular momentum and Planck's constant: both $[ML^2T^{-1}]$.
