Question

The maximum distance upto which TV transmission from a TV tower of height $h$ can be received is proportional to

• A. $h^{1/2}$
• B. $h$
• C. $h^{3/2}$
• D. $h^2$

Answer 1

The correct option is D $h^2$

If $r$ be the radius of the area upto which TV signal is visible, then $r=\sqrt{2Rh}$
where $R$ is the radius of the earth and $h$ is the height of the TV tower.

So, $r\propto \sqrt{h}$
