A TV tower has a height 160 m. Its coverage rangle is nearly (Earth's radius R= 6400 km)

A

45255 m

B

55265 m

C

452.55 km

D

552. 65 m

Text Solution

Verified by Experts

The correct Answer is:
A
Given height of a TV tower h =160 m
Radius of earth R = 6400 km =`6.4 xx10^(6)m` `d= sqrt(2R h) = sqrt( 2xx 6.4 xx 10^(6) xx 160) = 45254.8 45255m`
