    A uniform rope of length \[l\] lies on a table. If the coefficient of friction is \[\mu \] then the maximum length \[{{l}_{1}}\] of the part of this rope which can overhang from the edge of the table without sliding down is

    A)  \[\frac{l}{\mu }\]                            

    B)         \[\frac{l}{\mu +1}\]

    C)  \[\frac{\mu l}{1+\mu }\]                             

    D)         \[\frac{\mu l}{\mu -1}\]

    Correct Answer: C

    Solution :

    The length of the rope which can overhang from the edge of the table without sliding down is given by                 \[{{l}_{1}}=\left( \frac{\mu }{1+\mu } \right)l\]
