The correct formula for range of a transmitting antenna of height '2h' is:
(Given R = radius of the Earth)
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → $\sqrt{4Rh}$
The formula for range of transmitting antenna of height 'h' is -
$\sqrt{2Rh}$
for, $h=2h$
$⇒\sqrt{4Rh}$
