A light string passing over a smooth light pulley connects two blocks of masses

Question

m_{1}

and

m_{2}

(vertically). If the acceleration of the system is g/8 then the ratio of the masses is

Options:

A . 8 : 1

B . 9 : 7

C . 4 : 3

D . 5 : 3

Answer: Option B
:
B

a = (\frac{m_{2} - m_{1}}{m_{1} - m_{2}}) g = \frac{g}{g}

; by solving

\frac{m_{2}}{m_{1}} = \frac{9}{7}
