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 the earth to be 6.4 × 106 m)

(a) 100 km

(b) 24 km

(c) 55 km

(d) 50 km

To calculate the maximum signal transmission from any TV towers, the formula is –

d=\sqrt{2rh}=\sqrt{2\times 6.4\times 10^6\times 240}=55\: km

So, the distances up to which the signal can be received are (b) 24 km, (c) 55 km, (d) 50 km
