    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 [s = acceleration due to gravity]

    A) \[m=\frac{wg}{g-a}\]

    B) \[m=w\left( 1+\frac{a}{g} \right)\]

    C) the force of friction exerted by the rope on the monkey is \[m(g-a)N\]

    D) the tension in the rope is \[wg\,N\]

    Correct Answer: C

    Solution :

    The reading of the spring balance = tension in the rope = the force of friction between rope and the monkey \[=mg-ma\,=m(g-a)\,N\]
