The increase in the height of the tower of height 200 ~m to get its coverage range tripled is
Options
- A800 ~m
- B1600 ~m
- C900 ~m
- D700 ~m
Correct answer
B. 1600 ~m
Step-by-step solution
Given, height of the tower, h₁=200 ~m If R be the radius of the earth, then coverage range, d= 2 R h d h d₁ d₂ = h₁ h₂ array ll Since, & d₂=3 d₁ & d₁ 3 d₁ = h₁ h₂ array 1 3 = 200 h₂ 1 9 = 200 h₂ h₂=1800 ~m Increase in the height of the tower =1800 ~m -200 ~m =1600 ~m
