    An ice cart of mass 60 kg rests on a horizontal snow patch with coefficient of static friction \[\frac{1}{3}.\] Assuming that there is no vertical acceleration, find the magnitude of the maximum horizontal force required to move the ice cart. \[(g=9.8\,m{{s}^{-2}})\]

    A)  100 N                                   

    B)  110 N

    C)  209 N                                   

    D)  196 N

    Correct Answer: D

    Solution :

                     Force applied against friction \[{{f}_{k}}={{\mu }_{k}}R={{\mu }_{k}}\,mg=\frac{1}{3}\times 60\times 9.8\] \[=196\,N\]
