A TV transmission tower has a height of ...

A TV transmission tower has a height of 240 m. Signals broadcast from this tower will be received by LOS communication at a distance of (assume the radius of earth to be `6.4 xx 10 ^(6) m`)

A

100 km

B

24 km

C

55 km

D

50 km

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
In LOS communication maximum distance upto which a signals can be received from tower is
`d=sqrt(2rh)`
`=sqrt(2xx6.4xx 10^6xx240) `
`55xx 10^3 m`
`= 55 km`.
