Question
Population coverage P (number of people served) by a TV tower of height h placed in an area of population density η is:
- AP = η × 2πRh
- BP = η × π(2Rh)
- CP = η × πd² where d = √(2Rh)Correct
- DAll of these are equivalent
Correct answer
P = η × πd² where d = √(2Rh)
Explanation
Service area = πd² = π × 2Rh (circular area with radius = LOS distance). Population = η × π × 2Rh. Doubling tower height doubles coverage area and population served (linear relationship with h).
