Applications of Newton's Laws of Motion in Different Frames

Q 1 :
A light stretchable string passing over a smooth light pulley connects two blocks of masses $m_{1}$ and $m_{2}$ . If the acceleration of the system is $\frac{g}{8}$ , then the ratio of the masses $\frac{m_{2}}{m_{1}}$ is: [2024]

9 : 7
4 : 3
5 : 3
8 : 1

(A) $a_{c} = \frac{(m_{2} - m_{1}) g}{(m_{1} + m_{2})} \Rightarrow \frac{g}{8} = (\frac{m_{2} - m_{1}}{m_{1} + m_{2}}) g$

$\frac{1}{8} = (\frac{\frac{m_{2}}{m_{1}} - 1}{\frac{m_{2}}{m_{1}} + 1}) \Rightarrow \frac{m_{2}}{m_{1}} + 1 = 8 \frac{m_{2}}{m_{1}} - 8 \Rightarrow \frac{m_{2}}{m_{1}} = \frac{9}{7}$
