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

`82.6 km^(-2)`

B

`800.6 km^(-2)`

C

`828.6 km^(-2)`

D

`876.6 km^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`N=sigmapid^(2)`
`50 xx10^(5) =sigma xx(22)/(7)xx2xx6.4 xx10^(6)xx150`
`sigma = 828.6 km^(-2)`
