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

Options

  1. A9 7
  2. B8 1
  3. C4 3
  4. D5 3

Correct answer

A. 9 7

Step-by-step solution

Acceleration of the system can be written as, a = m 1 - m 2 g m 1 + m 2 = g 8 ⇒ 8 m 1 - 8 m 2 = m 1 + m 2 ⇒ 7 m 1 = 9 m 2 ⇒ m 1 m 2 = 9 7
