A light string passing over a smooth light pulley connects two blocks of masses m₁ and m₂ (where m₂>m₁ ). If the acceleration of the system is g 2 , then the ratio of the masses m₁ m₂ is:
Options
- A1+ 5 5 -1
- B2 -1 2 +1
- C1+ 5 2 -1
- D3 +1 2 -1
Correct answer
B. 2 -1 2 +1
Step-by-step solution
aligned & a= ( M₂-M₁ M₁+M₂ ) g & g 2 = ( M₂-M₁ M₁+M₂ ) g & (M₁+M₂ )= 2 M₂- 2 M₁ & M₁ M₂ = ( 2 -1 2 +1 ) aligned
