If momentum (P), area (A) and time (T) are taken to be the fundamental quantities then the dimensional formula for energy is:
- \(\left[\mathrm{PA}^{-1} \mathrm{~T}^{2}\right]\)
- \(\left[\mathrm{PA}^{\frac{1}{2}} \mathrm{~T}^{-1}\right]\)
- \(\left[\mathrm{P}^{2} \mathrm{AT}^{-2}\right]\)
- \(\left[\mathrm{F}^{\frac{1}{2}} \mathrm{AT}^{-1}\right]\)
Answer
(B) [ PA ^ 1 2 ~T ^ -1 ]
