Question

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.

Accepted Answer

Correct answer: 2. (2) Mass per unit length = λ N = mg = λ(L-x) g f s_m a x=μ_sN And also f s_m a x=m_xg 0.5 λ_(L−x_)g=λ x g L−x2=x L2= 3 x2⇒x= L3= 63=2 m
