Two masses m₁ and m₂ are connected by a light string passing over smooth pulley. When set free m₁ moves downwards by 3 m in 3 s . The ratio of m₁ m₂ is ( g =10 ~ms ⁻² )
Options
- A9 7
- B8 7
- C10 7
- D15 13
Correct answer
B. 8 7
Step-by-step solution
a= ( m₁-m₂ m₁+m₂ ) g Now, S=u t+ 1 2 a t^2 3=0+ 1 2 ( m₁-m₂ m₁+m₂ ) 10 (3)^2 aligned & m ₁- m ₂ ~m ₁+ m ₂ = 1 15 & ~m ₁ ~m ₂ = 8 7 aligned
