The correct answer is:
\(\sqrt{2} r\)
Range \(r=\sqrt{2 R h}\)
where \(R\) is the radius of the earth and \(h\) is the height of an antenna
\(\therefore \quad r^{\prime}=\sqrt{2 R(2 h)}=\sqrt{2}(\sqrt{2 R h})=\sqrt{2} r\)
where \(R\) is the radius of the earth and \(h\) is the height of an antenna
\(\therefore \quad r^{\prime}=\sqrt{2 R(2 h)}=\sqrt{2}(\sqrt{2 R h})=\sqrt{2} r\)
