A TV transmitter has a range of 50 ~km . The height of the TV transmitter is _________ (Radius of the earth, R_e=6 4 10^6 ~m )

Options

  1. A195.3 m
  2. B186.5 m
  3. C206 m
  4. D175 m

Correct answer

A. 195.3 m

Step-by-step solution

Range, d= 2 R_e h_T gathered 50 ~km = 2 6.4 10^6 h_T 2500 10^6=128 10^5 h_T 25000 128 =h_T h_T=195.3 gathered
