Concepts Of Physics MCQ Edition [Volume 1]PhysicsIntroduction to Physics
The dimensions ML⁻¹T⁻² can correspond to
Options
- Awork done by a force
- Bpressure
- Cenergy per unit volume
- Dlinear momentum
Correct answer
C. energy per unit volume
Step-by-step solution
Work done by a force = [MLT⁻²][L] = [ML^2T⁻²] Pressure = Force Area = [MLT⁻²] [L^2] = [ML⁻¹T⁻²] Energy per unit volume = Energy Volume = [ML^2T⁻²] [L^3] = [ML⁻¹T⁻²] Linear momentum = Mass Velocity = [M][LT⁻¹] = [MLT⁻¹] Both pressure and energy per unit volume correspond to the dimensions ML⁻¹T⁻² .
