A gun is used to fire a bullet at an angle of 30^ and at 60^ respectively. The ratios of heights and Ranges reached by the bullet are
Options
- A1: 3,1: 1
- B1: 1,1: 1
- C1: 1,3: 1
- D3: 1,1: 1
Correct answer
A. 1: 3,1: 1
Step-by-step solution
Maximum height: H = u^2 ^2 2g H₁ = u^2 ^2 30° 2g = u^2 8g , H₂ = u^2 ^2 60° 2g = 3u^2 8g H₁ : H₂ = 1 : 3 Range: R = u^2 2 g R₁ = u^2 60° g , R₂ = u^2 120° g Since 60° = 120° , R₁ = R₂ R₁ : R₂ = 1 : 1 Ratio of heights : ranges = 1:3, 1:1
