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 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
$\frac{l}{\mu }$
$\frac{l}{{\mu + l}}$
$\frac{{\mu l}}{{1 + \mu }}$
$\frac{{\mu l}}{{\mu - 1}}$
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
For given condition we can apply direct formula
${l_1} = \left( {\frac{\mu }{{\mu + 1}}} \right)\;l$
