Two physical quantities having the same dimensional formula [ M ^1 ~L ⁻¹ ~T ⁻² ] are
Options
- AThrust and Strain
- BWork and thrust
- CMoment of force and Thrust
- DStress and Pressure
Correct answer
D. Stress and Pressure
Step-by-step solution
The dimensional formula for Stress is Force Area = [M^1 L^1 T⁻²] [L^2] = [M^1 L⁻¹ T⁻²] . The dimensional formula for Pressure is Force Area = [M^1 L^1 T⁻²] [L^2] = [M^1 L⁻¹ T⁻²] . Since both Stress and Pressure have the same dimensional formula [M^1 L⁻¹ T⁻²] , they are the correct pair. Answer: Stress and Pressure
