MCQ
The physical quantity that has the same dimensional formula as pressure is :
- AForce
- BMomentum
- ✓Young's modulus of elasticity
- DCoefficient of viscosity
✓
Answer
Correct option: C.
Young's modulus of elasticity
c
$Y =\frac{\text { stress }}{\text { strain }} \text { (Strain is dimensionless) }$
$Y =\frac{\text { stress }}{\text { strain }} \text { (Strain is dimensionless) }$
$\therefore[ Y ]=[\text { stress }]=[\text { Pressure }]$
