The height of a transmitting antenna at the top of a tower is 25 m and that of receiving antenna is, 49 m . The maximum distance between them, for satisfactory communication in LOS (Line-Of-Sight) is K 5 × 10 2 m . The value of K is _____ . (Assume radius of Earth is 64 × 10 5 m ) [Calculate upto nearest integer value]
Correct answer
0
Step-by-step solution
Here, h T = 49 m ,   h R = 25 m ,   R = 64 × 10 5 m Maximum distance between two antennae is, d = 2 R h T + 2 R h R = 2 R 49 + 2 R 25 = 12 2 R = 12 2 × 64 × 10 5 = 192 5 × 10 2   m
