Solution

The correct option is A 2 m
Let y be the suspended length
Mass per unit length of chain =M6
Mass of the suspended part =M6y
For equilibrium of chain, the weight of suspended part must be balanced by force of fricion on the portion on the table.
μN=M6yg
μM(6y)g6=M6yg
12(6y)=y(6y)=2y
3y=6y=2 m
