A uniform chain of mass m and length l is lying on a frictionless horizontal table with one-third of its length hanging over the edge of the table. The amount of work done to pull the hanging part of the chain up to the table is given by
A uniform chain of length L and mass M is lying on a smooth table and one third of its length is hanging vertically down over the edge of the table. If g is acceleration due to gravity, the work required to pull the hanging part on to the table is [IIT 1985]
A uniform chain of mass M and length L is held on a horizontal frictionless table with 1nth of its length hanging over the edge of the table. The work done is pulling the chain up on the table is
