A monkey of mass $20\,kg$ is holding a vertical rope. The rope will not break when a mass of $25\, kg$ is suspended from it but will break if the mass exceeds $25 \,kg$. What is the maximum acceleration with which the monkey can climb up along the rope ............ $m/{s^2}$ $(g = 10\,m/{s^2})$

Tension the string $ = m\,(g + a)=$ Breaking force
$⇒$ $20(g + a) = 25 \times g$
$⇒$ $a = g/4 = 2.5\;m/{s^2}$
