Dimensional analysis MCQ: Pick the pair whose quantities do NOT have identical dimensions. Compare each pair using M–L–T dimensional formulae and identify the mismatch. Choose the correct option.

Difficulty: Easy

Force and weight
Pressure and stress
Angular momentum and Planck's constant (h)
Power and torque

Correct Answer: Power and torque

Explanation:

Check each pairForce vs weight ⇒ both MLT^-2.Pressure vs stress ⇒ both ML^-1T^-2.Angular momentum vs Planck's constant ⇒ both ML²T^-1.Power vs torque ⇒ ML²T^-3 vs ML²T^-2 (different).

Final AnswerPower and torque
