Strain

Vedclass · Answer

(C) The dimensional formula for $Young's  modulus$,$Stress$,and $Pressure$ is given by $\frac{Force}{Area} = \frac{[MLT^{-2}]}{[L^2]} = [ML^{-1}T^{-2}]$.$Strain$ is defined as the ratio of change in dimension to the original dimension,i.e.,$Strain = \frac{\Delta L}{L}$.Since $Strain$ is a ratio of two similar physical quantities,it is a dimensionless quantity,represented as $[M^0 L^0 T^0]$.Therefore,the dimensional formula $ML^{-1}T^{-2}$ does not represent $Strain$.

The dimensional formula $M L^{-1} T^{-2}$ does not represent which of the following physical quantities?
