Which of the following pairs has the same dimensions?
Model Answer & Options
Source: Extra PracticeImpulse and Momentum
Work and Power
Stress and Strain
Force and Pressure
Explanation
Impulse = Force × Time = [MLT⁻²][T] = [MLT⁻¹]. Momentum = Mass × Velocity = [M][LT⁻¹] = [MLT⁻¹]. Work [ML²T⁻²] and Power [ML²T⁻³] are different. Stress [ML⁻¹T⁻²] and Strain [dimensionless] are different. Force [MLT⁻²] and Pressure [ML⁻¹T⁻²] are different.
