A light unstretchable 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 :

Options

A $8: 1$
B $5: 3$
C $4: 3$
D $9: 7$

Correct answer

D. $9: 7$

Step-by-step solution

\begin{aligned} & a_{\text{sys }}=\left(\frac{m_2-m_1}{m_1+m_2}\right) g=\frac{g}{8} \\ & \Rightarrow \frac{m_2}{m_1}=\frac{9}{7}\end{aligned}
