one fourth chain is hanging down from
a table work done to bring the hanging
part of the chain on to the table is
(mass of chain = M and length=L)

Explanation:
fourth chain is hanging down from
a table work done to bring the hanging
part of the chain on to the table is
(mass of chain = M and length a call from god
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)
