```										Dear Eshita

mass of the hanging portion =(m/l) *l/3
=m/3

center of mass of the hanging portion from the top of the tabel  = l/6

work done = increse in potential energy =(m/3) *g * (l/6)
=mgl/18

But the force was not given with the question. There was no numerical value, just ‘F’. I’d be happy if you gave me the shortcut, though.
