Question

At what minimum acceleration a monkey should slide a rope whose breaking strength is $(\frac{2}{3}{)}^{rd}$ of its weight?

• A. $\frac{2g}{3}$
• B. $g$
• C. $\frac{g}{3}$
• D. $zero$

Answer 1

The correct option is C $\frac{g}{3}$

Let $a$ be the acceleration of monkey.
The apparent weight $=mg-ma=2mg/3$
or $ma=mg(1-2/3)=mg/3\Rightarrow a=g/3$
