A uniform chain of 6 m length is placed on a table such that a part of its length is hanging over the edge of the table. The system is at rest. The co-efficient of static friction between the chain and the surface of the table is 0.5, the maximum length of the chain hanging from the table is ___________ m.

Step-by-Step Verified Solution

(x)gλ=μ(6−x) gλ(x)g\lambda = \mu (6 - x)\,g\lambda where x is length of hanging part

⇒x=3−0.5x\Rightarrow x = 3 - 0.5x

⇒x=2\Rightarrow x = 2 m
