    A 500 kg horse pulls a can of mass 1500 kg along a level road with an acceleration of \[1\,m/{{s}^{2}}\]. If the coefficient of sliding friction is 0.2, then the horizontal force exerted by the earth on the horse is

    A)  300 kg-wt                          

    B)  400 kg-wt

    C)  500 kg-wt          

    D)         600 kg-wt

    Correct Answer: D

    Solution :

    Here, \[F-{{f}_{k}}=ma\] \[F={{f}_{k}}+ma\] \[F=\mu mg+ma\] \[F=m(\mu g+a)\]                 \[\therefore \]  \[F=(500+1500)(0.2\times 10+1)\]                                 \[F=6000\,N\]                                 \[f=6000\,kg-wt\]
