Gravitational potential energy has changed from the beginning to the chain just sliding away from the table willl be MgL/24.
<h3>What is gravitational potential energy?</h3>The energy that an item has due to its location in a gravitational field is known as gravitational potential energy.
Length of hanging part, L/4
The gravitational potential energy is;
Work = Gravitational potential energy
Work done =force×displacement
Hence, gravitational potential energy has changed from the beginning to the chain just sliding away from the table willl be MgL/24.
