A monkey of mass $m$ kg slides down a light rope attached to a fixed spring balance, with an acceleration $a$. The reading of the balance is $w kg [g=$ acceleration due to gravity $]$
- $m=\frac{w g}{g-a}$
- $m=w\left(1+\frac{a}{g}\right)$
- the force of friction exerted by the rope on the monkey is $ m(g-a)N $
- the tension in the rope is $ wg\,N $
The Correct Option is C

Concepts Used:
Kinetic energy
Kinetic energy of an object is the measure of the work it does as a result of its motion. Kinetic energy is the type of energy that an object or particle has as a result of its movement. When an object is subjected to a net force, it accelerates and gains kinetic energy as a result. Kinetic energy is a property of a moving object or particle defined by both its mass and its velocity. Any combination of motions is possible, including translation (moving along a route from one spot to another), rotation around an axis, vibration, and any combination of motions.
