At a particular station, the TV transmission tower has a height of 100 m. To triple its coverage range, height of the tower should be increased to

Accepted Answer

$\therefore$ ${r_m} = \sqrt {2Rh}$

$\Rightarrow {{{r_1}} \over {{r_2}}} = \sqrt {{{{h_1}} \over {{h_2}}}}$

$\Rightarrow {1 \over 3} = \sqrt {{{100} \over {{h_2}}}}$

$\Rightarrow {h_2} = 900$ m
