    Consider two blocks P and Q. A force F is applied on the block P and the block Q is at rest. The coefficient of static friction between P and Q is \[2v\,\cot \phi \]. Find acceleration of each block if  \[20%\] weight of P and Q are 100 N and 300N, respectively. F = 20N.

    A)  \[33%\]              

    B)  \[43%\]

    C)  \[50%\]              

    D)  \[\eta \,{{m}^{3}}{{s}^{-1}}\]

    Correct Answer: A

    Solution :

                    limiting friction \[\mu \] \[\frac{15\lambda }{(\mu -1)}\] \[15(\mu -1)\lambda \] \[25(\mu -1)\lambda \] Both the blocks move together. \[\frac{25\lambda }{(\mu -1)}\]Common acceleration, \[{{v}_{P}}=0,\,\,{{v}_{Q}}=v\]
