The monkey $B$ shown in figure is holding on to the tail of the monkey $A$ which is climbing up a rope. The masses of the monkeys $A$ and $B$ are $5 k g$ and $2 k g$ respectively. If $A$ can tolerate a tension of $30 N$ in its tail, what force maximum should it apply on the rope in order to carry the monkey $B$ with it? Take $g = 10 m / s^{- 2}$ .

Solution

The correct option is A $105 N$
Given, $M a s s, M_{1} = 5 k g, m_{2} = 2 k g, F = 30 N$

So, $T - F_{g} - 30 - 5 a = 0......1$

$30 - 2 g - 2 a = 0.........2$

Multiply by 2 in inequation 1 and equation by 5 and solving them then we get,

$T = 105 N$ and $a = 5 m / s^{2}$

Thus the maximum force applied by the monkey A to carry monkey B is $105 N$
