    Consider a track having frictional coefficient \[\mu .\]A block of mass m is released from point P situated at height \[h.\]Which of the following is correct?

    A)  It can reach at V

    B)  It cannot reach at V

    C)  It can reach at V, if \[\mu \]is reduced to \[\mu /2\]

    D)  It can reach at V, if \[\mu \]is increased to\[2\mu \]

    Correct Answer: B

    Solution :

     The block can reach at V only when there is no loss in kinetic energy. In this case, due to presence of friction dissipation of energy will take place. Thus, the particle cannot reach at V.
