The increase in the height of the tower of height \(200 \mathrm{~m}\) to get its coverage range tripled is
- A \(800 \mathrm{~m}\)
- B \(1600 \mathrm{~m}\)
- C \(900 \mathrm{~m}\)
- D \(700 \mathrm{~m}\)
Answer & Solution
Correct Answer
(B) \(1600 \mathrm{~m}\)
Step-by-step Solution
Detailed explanation
Given, height of the tower, \(h_{1}=200 \mathrm{~m}\) If \(R\) be the radius of the earth, then coverage range, \(d=\sqrt{2 R h} \Rightarrow d \propto \sqrt{h}\) \(\Rightarrow \quad \frac{d_{1}}{d_{2}}=\sqrt{\frac{h_{1}}{h_{2}}}\)…
