The physical quantity that has the same dimensional formula as pressure is (a) Coefficient of viscosity (b) Force (c) Momentum (d) Young's modulus of elasticity

Answer: (d). Pressure = F/A: ML⁻¹T⁻². Young's modulus = stress/strain = stress: ML⁻¹T⁻². Viscosity ML⁻¹T⁻¹, force MLT⁻², momentum MLT⁻¹ differ. So the answer is (d).

The physical quantity that has the same dimensional formula as pressure is

Show answer and solution

Answer: (d)

Pressure $= F/A$ : $\mathrm{ML^{-1}T^{-2}}$ .
Young's modulus $=$ stress/strain $=$ stress: $\mathrm{ML^{-1}T^{-2}}$ .
Viscosity $\mathrm{ML^{-1}T^{-1}}$ , force $\mathrm{MLT^{-2}}$ , momentum $\mathrm{MLT^{-1}}$ differ.
So the answer is (d).
