The maximum distance between the transmitting and receiving TV towers is 65 ~km . If the ratio of the heights of the TV transmitting tower to receiving tower is 36: 49 , the heights of the transmitting and receiving towers respectively are (radius of earth =6400 ~km )
Options
- A51.2 m, 80 m
- B70.3 m, 95.7 m
- C30 m, 65 m
- D25 m, 75 m
Correct answer
B. 70.3 m, 95.7 m
Step-by-step solution
From Eqs. (i) and (ii), we get and aligned & h_T=70.3 ~m & h_R=95.7 ~m aligned
