a uniform chain of lenght 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,calculate work required to pull the hanging part on th table

Suppose length of an element at distance x from the table=dx

Let us consider that the mass of the hanging part is concentrated at the centre of gravity of hanging part.

Work done required to pull the hanging part on the table,
