A rope placed straight on a frictionless floor is pulled longitudinally by a force F. Tension force T developed in the rope at a point varies with distance x of the point from the rear end as shown in the graph. What can you certainly conclude about density of the rope?

Options

A. It is uniform.
B. It decreases with distance x from the rear end.
C. It increases with distance x from the rear end.
D. It is maximum in the middle and decreases towards the ends.

Answer

B

Explanation

As initially, tension force 'T' increases rapidly so density of the rope is more near the rear end.
