In communication with help of antenna if height is doubled then the range covered which was initially (r ) would become
Options
- A( 2 r )
- B(3 r )
- C(4 r )
- D(5 r )
Correct answer
A. ( 2 r )
Step-by-step solution
Range (r= 2 R h ) where (R ) is the radius of the earth and (h ) is the height of an antenna ( r^ = 2 R(2 h) = 2 ( 2 R h )= 2 r )
