A chain of mass m and length L is over hanging , from the edge of a smooth, horizontal table such that , 3/4th of its length is lying on , the table .The work done in pulling the chain completely , on to the table is

A uniform chain of mass m & length L is kept on a smooth horizontal table such that (L)/(n) portion of the chaing hangs from the table. The work dione required to slowly bringsthe chain completely on the table is

A uniform rope of length 'L and linear density 'mu' is on a smooth horizontal table with a length 'I' lying on the table. The wrok done in pulling the hanging part on to the table is

A uniform chain has mass Mand length L. It is lying on a smooth horizontal table with half of its length hanging vertically downward. The work done in pulling the chain up 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 chain of mass M is placed on a smooth table with 1/n of its length L hanging over the edge. The work done in pulling the hanging portion of the chain back to the surface of the table is:

A chain of uniform mass m and length L is held on a frictionless table in such a way that its (1)/(n) th part is hanging below the edge of table. The work done to pull the hanging part of chain is :-

A uniform chain has a mass m and length l . It is held on a frictionless table with one - sixth of its length hanging over the edge. The work done in just pulling the hanging part back on the table is :

A uniform chain of mass M and length L is lying on a frictionless table in such a way that its 1//3 parts is hanging vertically down. The work done in pulling the chain up the table is

A uniform rope of length 3 m and mass 1 kg is kept on a table such that 80 cm of its length hangs freely from the edge of the table . Calculate the work done in pulling the entire rope on 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 :
