The height of transmitting antenna if TV programs have to cover the population in area of radius is
[Use Radius of earth ]
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
The formula of range of transmitting signal for a TV program for a transmitting antenna in terms of the height of the antenna and radius of the earth is, d=2Reh, here Re=6.4×106 m and d=64×103 m, it means, h=d22Re=6400022×6.4×106=320 m
