Detailed Solution

For the chain to be in equilibrium,

assuming $l$ is the length of he chain hanging

Weight of the hanging part is offset by the frictional force on the resting part.

$\Rightarrow (\frac{M}{L}) l g = μ (\frac{M}{L}) (L - l) g$

By solving this equation for $l$ ,

$l = \frac{μL}{1+μ}$
