A chain of length L has a mass of m which is uniformly distributed. When it is placed on a smooth horizontal table, 1/4 of its l
ength hangs over the edge of the table (as shown in the figure). Then the chain slides away from the table freely, how much gravitational potential energy has changed from the beginning to the chain just sliding away from the table? (The height of the table from the ground is much greater than L)
1 answer:
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.

Answer:
<h3>The answer is 12 m/s²</h3>Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>12 m/s²</h3>Hope this helps you
