What is the minimum force needed to pull the moving part ?

A chain of mass m=0.80kg and length l=1.5m rests on a rough-surfaced table so that one of its ends hangs over the edge. The chain starts sliding off the table all by itself provided the overhanging part equals eta=1//3 of the chain length. What will be the total work performed by the friction forces acting on the chain by the moment it slides completely off the table?
