Vedclass · Answer

(C) The dimensions of the given quantities are as follows:$1$. Speed: $[LT^{-1}]$ and ${({\mu _0}{\varepsilon _0})^{-1/2}} = c$ (speed of light): $[LT^{-1}]$. They have the same dimensions.$2$. Torque: $[ML^2T^{-2}]$ and Work: $[ML^2T^{-2}]$. They have the same dimensions.$3$. Momentum: $[MLT^{-1}]$ and Planck's constant: $[ML^2T^{-1}]$. They do not have the same dimensions.$4$. Stress: $[ML^{-1}T^{-2}]$ and Young's modulus: $[ML^{-1}T^{-2}]$. They have the same dimensions.Therefore,the correct option is $C$.

The physical quantities not having the same dimensions are:
