Question 68: Laws of Motion

Question

A light string passing over a smooth light fixed pulley connects two blocks of masses $$m_1$$ and $$m_2$$. If the acceleration of the system is $$g / 8$$, then the ratio of masses is:

Accepted Answer

$$\begin{aligned}
& a=\frac{\left(m_1-m_2ight) g}{\left(m_1+m_2ight)}=\frac{g}{8} \
& 8 m_1-8 m_2=m_1+m_2 \
& 7 m_1=9 m_2 \
& \frac{m_1}{m_2}=\frac{9}{7}
\end{aligned}$$

Answer

$$\frac{8}{1}$$

Answer

$$\frac{9}{7}$$

Answer

$$\frac{5}{3}$$

Answer

$$\frac{4}{3}$$
