Questions
The maximum distance between the transmitting and receiving antenna TV tower is D. If the heights of both towers are halved then maximum distance between them becomes
detailed solution
Correct option is B
Initially , hT1=hT hR1=hR D1=D ∴D1=2RhT1+2RhR1 -------(1) Finally , hT2=hT2 hR2=hR2 D2=? ∴D2=2RhT2+2RhR2 =2RhT12+2RhR12 =2RhT12+2RhR12 =2RhT1+2RhR12 =D2 [Using equation (1)]Talk to our academic expert!
