A TV tower has a height \(72 \mathrm{~m}\). The maximum distance upto which TV transmission can be received is (Take, radius of the earth as \(\left.6.4 \times 10^6 \mathrm{~m}\right)\)
- A 30.36 km
- B 25.12 km
- C 27.52 km
- D 34.25 km
Answer & Solution
Correct Answer
(A) 30.36 km
Step-by-step Solution
Detailed explanation
The maximum distance \(d\) up to which the TV transmission can be received from a tower of height \(h\) is given by the formula \(d = \sqrt{2Rh}\), where \(R\) is the radius of the Earth. Given values are \(h = 72 \text{ m}\) and \(R = 6.4 \times 10^6 \text{ m}\). Substituting…
