A chain of mass m and length l is placed on a table with one-sixth of it hanging freely from the table edge. The amount of work. done to pull the chain on the table is

A uniform chain of mass m and length l is kept on a horizontal table with half of its length hanging from the edge of the table.Work done in pulling the chain on to the table so that only 1/5 th of its length now hangs from the edge is K((mgl)/(200)) .Find the value of K.

A unifrom chain of mass M and length L lies on a table with nth part of it hanging off the table. Find the work required to slowly pull the hanging part up to the table.

A uniform chain of length l and mass m is placed on a smooth table with one-fourth of its length hanging over the edge. The work that has to be done to pull the whole chain back onto the table is :
