Dimensional formula identification: ML²T⁻² corresponds to which physical quantity? Use standard M–L–T dimensional analysis for mechanical quantities. Choose the correct option.

Q: Dimensional formula identification: ML²T⁻² corresponds to which physical quantity? Use standard M–L–T dimensional analysis for mechanical quantities. Choose the correct option.

Derivation Work = Force × distance = (MLT-2) × L = ML2T-2.Torque = r × F has the same dimensions ML2T-2. Contrast Power = Work/time ⇒ ML2T-3; Momentum = MLT-1; Pressure = ML-1T-2. Final Answer Work or energy (also torque)

Difficulty: Easy

Power
Work or energy (also torque)
Linear momentum
Pressure

Correct Answer: Work or energy (also torque)

Explanation:

Derivation
Work = Force × distance = (MLT^-2) × L = ML²T^-2.Torque = r × F has the same dimensions ML²T^-2.

Contrast
Power = Work/time ⇒ ML²T^-3; Momentum = MLT^-1; Pressure = ML^-1T^-2.

Final Answer
Work or energy (also torque)
