The maximum tension a rope can withstand is \(60 \mathrm{~kg}\)-wt. The ratio of maximum acceleration with which two boys of masses \(20 \mathrm{~kg}\) and \(30 \mathrm{~kg}\) can climb up the rope at the same time is
- A 1 : 2
- B 2 : 1
- C 4 : 3
- D 3 : 2
Answer & Solution
Correct Answer
(D) 3 : 2
Step-by-step Solution
Detailed explanation
\(\begin{aligned} 60 \mathrm{~kg}-\mathrm{wt} & =20\left(g+a_1\right)+30\left(g+a_2\right) \\ = & 20 \mathrm{~kg}-\mathrm{wt}+30 \mathrm{~kg}-\mathrm{wt}+20 a_1+30 a_2\end{aligned}\)…
