Question

Dimensional formula $M{L}^2{T}^{-2}$ does not represent the physical quantity

• A. Young's modulus of elasticity
• B. Stress
• C. Strain
• D. Pressure

Answer 1

The correct option is D Pressure

We know work done is equal to change in energy. So work done and energy has same units.

Energy = $\left[M{L}^2{T}^{-2}\right]$

Force = $mass\times accelaration$ = $\left[ML{T}^{-2}\right]$
