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

`82.6 km^(-2)`

`800.6 km^(-2)`

`828.6 km^(-2)`

`876.6 km^(-2)`

Text Solution

Verified by Experts

The correct Answer is:

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