Question

One end of a rope of mass M and length L is pulled by applying a contant horizontal force I'. Ground is rough with coellicient of friction m. It is given that (riction is insuſſicient to prevent slipping. Tension at a distance x from the end where force is applied is : F z​

Answer 1

Answer:

As the center of mass of the rope is at the mid point of it, the tension is equal to the Applied force−Friction force.

⇒T=F−μN=Mg−

Mg

Answer 2

Explanation:

A rope of length L and mass M is being pulled on a rough horizontal floor by a constant horizontal force F = Mg. 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
