Q 11-01-045NEETJEE MainMedium
If force ($F$), length ($L$) and time ($T$) are taken as fundamental quantities, the dimensional formula of mass is
Answer: (B) $[FL^{-1}T^{2}]$
From $F = ma$, we get $m = \dfrac{F}{a}$. Acceleration has dimensions $[LT^{-2}]$, so
$$[m] = \frac{[F]}{[LT^{-2}]} = [FL^{-1}T^{2}]$$
