    The Martians use force \[(F)\], acceleration \[(A)\] and time \[(T)\] as their fundamental physical quantities. The dimensions of length on Martians system are                                                               [DCE 1993]

    A)             \[F{{T}^{2}}\]        

    B)             \[{{F}^{-1}}{{T}^{2}}\]

    C)             \[{{F}^{-1}}{{A}^{2}}{{T}^{-1}}\]

    D)               \[A{{T}^{2}}\]

    Correct Answer: D

    Solution :

                    Acceleration = \[\frac{\text{distan}\text{ce}}{\text{tim}{{\text{e}}^{2}}}\]Þ\[A=L{{T}^{-2}}\Rightarrow L=A{{T}^{2}}\]
