    A)  1000kg                                

    B)  1kg

    C)  10000kg              

    D)  100kg

    Correct Answer: C

    Solution :

                    Let\[x\]kg be unit of mass, then \[F={{(x\,kg)}^{1}}{{(1000\,m)}^{1}}{{(100\,s)}^{-2}}\] \[1000=x\times 1000\times \frac{1}{10000}\]                 \[x=10000\,kg\]                 \[x={{10}^{4}}\,kg\]
