A chain of mass m and length l rests on a rough table with part overhanging. The chain starts sliding down by itself if overhanging part is l/3. What will be the work performed by the friction force acting on the chain by the moment it slides completely off the table.

Text Solution
Verified by ExpertsThe correct answer is:
D

Assume at any instant the length of the chain on the table is x then force friction = μ μ N =
xg
Work done against friction
xg. dx
=
