    A body of mass 10 kg is lying on a rough plane inclined at an angle of 30° to the horizontal and the coefficient of friction is 0.5. The minimum force required to pull the body up the plane is

    A)  914 N                                   

    B)  91.4 N

    C)  9.14 N                                 

    D)  0.914 N

    Correct Answer: B

    Solution :

                     \[F=mg(sin\theta +\mu cos\theta )\] \[=10\times 9.8(sin{{30}^{o}}+0.5\cos {{30}^{o}})\] \[=91.4\,N\]
