Q. The Martians use force $(F),$ acceleration $(A)\$and time $(T)$ as their fundamental physical quantities. The dimensions of length on Martians system are
A) $FT^{2}$
B) $F^{- 1}T^{2}$
C) $F^{- 1}A^{2}T^{- 1}$
D) $AT^{2}$
Explanation
Acceleration = $\frac{Distance}{time^{2}} \Rightarrow A = LT^{- 2} \Rightarrow L = AT^{2}$
