In a line of sight radio communication, a distance of about $\displaystyle 50$ km is kept between the transmitting and receiving antennas. If the height of the receiving antenna is $\displaystyle 70$ m, then the minimum height of the transmitting antenna should be :
(Radius of the Earth $\displaystyle =6.4 \times 10^6 \mathrm{~m}$ ).
Official answer
(2)
$\displaystyle 32$ m
