Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

Question

Answer in picture containing the question. Kindly before submitting the solution.

27. A uniform rope of mas m and length l is spread out on a horizontal
frictionless surface, wrapping half turn around a fixed vertical
frictionless cylinder of radius r< l. Initially, both the ends of the rope
are pulled by equal forces each F in magnitude keeping both the
unwrapped segments parallel to each other and equal in length as
shown in the figure. Suddenly pulling force at one end is removed
without any change in the pulling force at the other end. After how much
time from removal of the pulling force at an end, will the rope start
losing contact with the cylinder? Pus ML (1-)
