A light string passing over a smooth light pulley connects 2 blocks of...
Solution:

Given, acceleration of the system = g/8

Let the masses of the blocks be m1 and m2

The force acting on m1 is T - m1g (where T is the tension in the string)

The force acting on m2 is m2g - T

Using Newton's second law of motion,

For m1, T - m1g = m1 (g/8)

=> T - m1g = (m1g)/8

=> T = (9/8)m1g

For m2, m2g - T = m2 (g/8)

=> T = (7/8)m2g

Equating T from both the equations, we get

(9/8)m1g = (7/8)m2g

=> m1/m2 = 7/9

Therefore, the ratio of the masses is 4:3 (Option C)
