    If force (F), length (I) and time (T) are assumed to be the fundamental units, then the dimensional formula of the mass will be :

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

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

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

    D)  \[[F{{L}^{2}}{{T}^{2}}]\]

    Correct Answer: A

    Solution :

                    From Newton's second law Force (F) = Mass (M)\[\times \]acceleration \[\therefore \]  Dimensions of \[[F]=[ML{{T}^{-2}}]\] \[\Rightarrow \]               \[[M]=[F{{L}^{-1}}{{T}^{2}}]\]
