The ratio of weight of a man in a stationery lift and weight when the lift is moving downward with a uniform acceleration ' a ' is 3: 2 . Then the value of ' a ' is
Options
- A3 2 ~g
- Bg 3
- C2 3 ~g
- Dg
Correct answer
B. g 3
Step-by-step solution
Weight of a man when the lift is stationary, W ₁= mg . Weight when the lift is going down, W ₂= m ( g - a ) array ll & W₁ W₂ = m g m(g-a) = 3 2 & g g-a = 3 2 & 2 g=3 g-3 a & g=3 a & a= g 3 array ....(Given)
