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

Correct Option - 3


Detailed Solution:

Final range = 3 Initial Range

$\Rightarrow d_f=3d_i$ $\begin{array}{l}\Rightarrow \sqrt[]{2h\text{'}R}=3\sqrt[]{2hR}\\ \Rightarrow h\text{'}=9h=900m\end{array}$
