Q. 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) $\frac{1}{\mu}$
B) $\frac{1}{\mu + l}$
C) $\frac{\mu l}{1 + \mu}$
D) $\frac{\mu l}{\mu - 1}$
Explanation
(c) For given condition we can apply direct formula
$l_{1} = \left( \frac{\mu}{\mu + 1} \right)l$
