6The net displacement of com is l/2+l/2=l
so the work done will be mgl
is it correct?
bahut dino baaaaaad!!! hope this is not a repitition of one of the previous ones!!!
a book was kept on table and it was turned to turn it upside down!!

1it is not quite logical still u missed something subho still [1].indeed two more things lOL

1answer is Mg(l2) since initially raising centre of mass by l/2 and rest work is done by gravity
so workdone against gravity = Mg(l2)
1ohh ...but u din mention tat the velocity during taking up is negligible n thel its free fall..................
i mean if we take dis thing very slowly ateach step...then work done = change in potential energy = 0...
