A T V transmitter has a range of 50 km . The height of the T V 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

Recall the height of TV transmission is, h = d 2 2 R e , where d is the range of TV transmission, ⇒ h = d 2 2 R e = 50000 2 2 6 . 4 × 10 6 = 195 . 3   m
