A rope of length `L` and mass `M` is being pulled on a rough horizontal floor by a constant horizontal force `F = m g`. The force is acting at one end of the rope in the same direction as the length of the rope. The coefficient of kinetic friction between rope and floor is `1//2`. Then the tension at the midpoint of the rope is
