Friction on horizontal surface

Question

A homogeneous chain lies in limiting equilibrium on a horizontal table of coefficient of friction 0.5 with part of it hanging over the edge of the table. The fractional length of the chain hanging down the edge of the table is

Moderate

A

1/2
B

1/5
C

1/3
D

2/3

Solution

$\frac{x}{l} = \frac{\mu }{{1 + \mu }}Given\;\mu = 0.5$
$\frac{x}{l} = \frac{{1/2}}{{1 + 1/2}} = \frac{{1/2}}{{3/2}} = \frac{1}{3}$
Fractional length = 1/3
