MCQ
Which physical quantities have the same dimension
- ✓Couple of force and work
- BForce and power
- CLatent heat and specific heat
- DWork and power
✓
Answer
Correct option: A.
Couple of force and work
(a)
$ { Couple of force }=|\vec{r} \times \vec{F}|=\left[M L^2 T^{-2}\right]$
$\text { Work }=[\vec{F} \cdot \vec{d}]=\left[M L^2 T^{-2}\right]$
$ { Couple of force }=|\vec{r} \times \vec{F}|=\left[M L^2 T^{-2}\right]$
$\text { Work }=[\vec{F} \cdot \vec{d}]=\left[M L^2 T^{-2}\right]$
