A uniform chain of mass M and length L lies on a horizontal table such that one third of its length hangs from the edge of the table. The work done in pulling the hanging part on the table will be:

A uniform chain of mass m and length l is lying on a horizontal table with one-third of its length hanging over the edge of the table. If a gentle push is given to hanging end, it will start moving down. What is the change in gravitational potential energy of the chain, as it just leaves the table?

A uniform chain of mass m and length l is lying on a horizontal table with one-third of its length hanging over the edge of the table. If the chain is limiting equlibrium, what is the coefficient of friction for the contact between table and chain?

A uniform chain of mass m and length l is lying on a horizontal table with one-third of its length hanging over the edge of the table. What is the speed of the chain, when it just loses contact with the table?

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 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 of mass 4 kg and length 2 m is kept on table such that 3//10^("th") of the chain hanges freely from the edge of the table. How much work has to be done in pulling the entire chain on the table?

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 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 :

A uniform chain of length l is placed on a smooth horizontal table, such that half of its length hangs over one edge. It is releasedfrom rest, the velocity with which it leaves the table is

A chain of mass m and length l lies on a horizontal table. The chain is allowed to slide down gently from the side of the table. Find the speed of the chain at the instant when last link of the chain slides from the table. Neglect friction everywhere. (a) the force from thelicopter and (b) the gravitational force on her (c ) What are speed ot the kinetic energy and. (d) the speed of the astronaut just before she reaches the helicopter?
