Question

At what minimum acceleration should a monkey slide down a rope whose breaking strength is two-thirds of the monkey's weight?

• A. g
• B.
• C.
• D. 2g

Answer 1

The correct option is B

When a monkey is sliding down a rope, the net force acting on it is given by
ma = mg - T, where T is the breaking strength of the rope
$\Rightarrow$ ma = mg - $\frac{2}{3}$ mg
$\Rightarrow$ a = $\frac{g}{3}$
