What should be the height of transmitting antenna and the population covered if the television telecast is to cover a radius of $\displaystyle 150$ km ? The average population density around the tower is $\displaystyle 2000 / \mathrm{km}^2$ and the value of $\displaystyle \mathrm{R}_{\mathrm{e}}=6.5 \times 10^6 \mathrm{~m}$.
Official answer
(3)
Height $\displaystyle =1731 \mathrm{~m}$
Population Covered $\displaystyle =1413 \times 10^5$
