Q. Which physical quantities have the same dimension
A) Couple of force and work
B) Force and power
C) Latent heat and specific heat
D) Work and power
Explanation
Couple of force = $\left| \overrightarrow{r} \times \overrightarrow{F} \right| = \lbrack ML^{2}T^{- 2}\rbrack$ Work $= \left\lbrack \overrightarrow{F}.\overrightarrow{d} \right\rbrack = \lbrack ML^{2}T^{- 2}\rbrack$
