A TV transmission tower has a height of $\displaystyle 140$ m and the height of the receiving antenna is $\displaystyle 40$ m . What is the maximum distance upto which signals can be broadcasted from this tower in LOS(Line of Sight) mode ? (Given : radius of earth $\displaystyle =6.4 \times 10^6 \mathrm{~m}$ ).
Official answer
(3)
$\displaystyle 65$ km
