In communication with help of antenna if height is doubled then the range covered which was initially r would become
Options
(a) √2r
(b) 3r
(c) 4r
(d) 5r
Correct Answer:
√2r
Explanation:
Range r = √(2Rh)
Where R is the radius of the earth and h is the height of the antenna
.·. r’ = √[2R(2h)] = √2 [√(2Rh)] = √2 r
