A TV. Tower has a height 150 m.What is the population density around the TV. Tower if the total population covered is 50 lakh? (radius of earth `=6.4xx10^(6)m`)

A

`708.5 km^(-2)`

B

`828.6 km^(-2)`

C

`856.8 km^(-2)`

D

`454 km^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Population covered `= rho pi d^(2)`
`50 xx 10^(5) = rho (pi hR)`
`:. Rho = (50 xx 10^(5))/(3.14 xx 2 xx 150 xx (6.4 xx 10^(6))) = 828.6 km^(-2)`
