  • question_answer
    If force (F) velocity (\[\upsilon \]) and time (T) are taken as fundamental units, then the dimensions of mass are [AIPMT 2014]

    A)  \[[Fv{{T}^{-1}}]\]

    B)  \[[Fv{{T}^{-2}}]\] 

    C)  \[[F{{v}^{-1}}{{T}^{-1}}]\]

    D)  \[[F{{v}^{-1}}T]\]

    Correct Answer: D

    Solution :

    We know that \[F=ma\Rightarrow F=\frac{mv}{t}\Rightarrow m=\frac{Ft}{v}\] \[[M]=\frac{[F][T]}{[v]}=[F{{v}^{-1}}T]\]
