A monkey of mass climbs on a rope. The rope can stand a maximum tension of . In which of the following cases will the rope break:
climbs up with an acceleration of
Explanation for the correct option:
Step 1: Given data in the question.
In the question, it is given that a monkey of mass climbs on a rope and the rope can stand a maximum tension of .
Step 2: Concept to be used.
The tension in an inextensible and weightless string can be given by the sum of the weight hanging from it and the force acting on it.
Step 3: Find the maximum acceleration at which the monkey can climb the rope without breaking it.
Assume that it monkey is climbing in the upward direction with the acceleration of .
So, the total tension on the rope is given as:
where is the mass of the monkey.
Since, the mass of the monkey is and the maximum tension rope can handle is .
So,
Therefore, the maximum acceleration at which the monkey can climb the rope is .
Since, In the option it is given that the monkey climbs up with an acceleration of which is greater than the maximum allowed acceleration.
Therefore, the rope will break when the monkey climbs up with an acceleration of .
Hence, option is the correct answer.
