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

Difficulty: Easy

Correct Answer: Work or energy (also torque)

Explanation:

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

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

Final AnswerWork or energy (also torque)
