The maximum distance between the transmi...

The maximum distance between the transmitting and receiving TV towers is `D`. If the heights of both transmitting and receiving towers are doubled then the maximum distance between them becomes

A

`2D`

B

`sqrt(2)D`

C

`4D`

D

`D//2`

Text Solution

Verified by Experts

The correct Answer is:
B
`s=sqrt(2Rh_(T))+sqrt(2Rh_(R))` when both `h_(T)` and `h_(R)` are doubled then s becomes `sqrt(2) "times"`.
