Solution Preview

The fig. shows 3.4 m of the rope on the bench and 0.6 m hanging down.
Total mass of the rope = 0.4 kg
Mass per unit length = 0.4/4 = 0.1 kg/m
Force on the rope is on account of the weight of its hanging portion.
Hence, initial force acting on the rope (trying to pull it down from the bench) = Mass of the hanging portion x g = Length of the hanging portion x Mass per unit length x g = 0.6 x ...
