Answer:

so here we have to find the work done by the force

Explanation:

special point

 here chain force equal to the weight of the hanging part...because it's like in equilibrium or rest like a position...

look at the picture given

so the weight of the hanging part acts from the middle of the hanging chain, therefore we have to use only the length above that point simply (above the center of gravity)

so THE length of the hanging part is (L/4)...THEN center of gravity acts in the middle, therefore length become half again

so the new length is (L/8)

AND YOU MUST KNOW THE WAY FIND THE WEIGHT OF HEAVY ROPE OR CHAINS (IT'S IN THE PICTURE)
