NEET2022PhysicsUnits and DimensionsActual
The physical quantity that has the same dimensional formula as pressure is:
Options
- AForce
- BMomentum
- CYoung's modulus of elasticity
- DCoefficient of viscosity
Correct answer
C. Young's modulus of elasticity
Step-by-step solution
Dimensions of Pressure = [ ML ⁻¹ ~T ⁻ . . ^2 ] Dimension of Force = [ MLT ⁻² ] Dimension of Momentum = [ MLT ⁻¹ ] Dimension of Young's modulus of elasticity = [ ML ⁻¹ ~T ⁻² ] Dimension of coefficient of viscosity = [ ML ⁻¹ ~T ⁻¹ ]
