A TV tower has a height of \(5 \mathrm{~m}\) in a region of population density \(\frac{1000}{\pi}\) per square kilometre. Number of people that can receive the transmission is nearly, (in thousands)
- A 128
- B 64
- C 256
- D 32
Answer & Solution
Correct Answer
(B) 64
Step-by-step Solution
Detailed explanation
Given, height of a TV tower, \(h=5 \mathrm{~m}\) population density, \(n=\frac{1000}{\pi}\) Now, the maximum range of this transmission depends upon the height of transmitting antenna and is given by \(d=\sqrt{2 h R_e}\). where, \(h=\) height of tower and \(R_e=\) Radius of…
