    A body A of mass 1 kg rests on a smooth surface. Another body B of mass 0.2 kg is placed over A as shown. The coefficient of static friction between A and B is 0.15. B will begin to slide on A, if A is pulled with a force greater than

    A)  1.764N                

    B) 0.1764 N

    C)  0.3 N               

    D) It will not slide for any F

    Correct Answer: A

    Solution :

    B will begin to slide on A, if pseudo force is more than limiting friction \[{{x}_{2}}\] \[{{x}_{1}}\]\[[{{M}^{0}}L{{T}^{2}}]\] \[[{{M}^{0}}{{L}^{2}}{{T}^{-4}}]\]\[[{{M}^{0}}L{{T}^{-3}}]\]
