A light string passing over a smooth light pulley connects two blocks of masses m ₁ and m ₂ (where m₂ m₁ ). If the acceleration of the system is g 2 , then the ratio of the masses m₁ m₂ is:

Options

  1. A2 -1 2 +1
  2. B1+ 5 5 -1
  3. C1+ 5 2 -1
  4. D3 +1 2 -1

Correct answer

A. 2 -1 2 +1

Step-by-step solution

Acceleration is given as: a= ( m₂-m₁ m₁+m₂ ) g g 2 = ( m ₂- m ₁ ~m ₁+ m ₂ ) g 2 (m₂-m₁ )=m₁+m₂ m ₁ ~m ₂ = ( 2 -1 2 +1 )
