If three objects are thrown with velocity 2 g H 3 , 2 gH , g H 3 , then find the ratio of their maximum heights.

Options

  1. A2: 6: 1
  2. B2: 5: 3
  3. C2: 4: 7
  4. D3: 7: 4

Correct answer

A. 2: 6: 1

Step-by-step solution

Maximum height of projectile H _ = u ^2 2 ~g aligned & ( H _ )₁: ( H _ )₂: ( H _ )₃ &= ( 2 gH 3 )^2 2 ~g : ( 2 gH )^2 2 ~g : gH 3 2 ~g = 2 3 : 2: 1 3 & =2: 6: 1 aligned
