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)`

A

`82.6 km^(-2)`

B

`800.6 km^(-2)`

C

`828.6 km^(-2)`

D

`876.6km^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`N=sigma pi d^(2)`
`50xx10^(5) =sigmaxx22/7xx2xx6.4 xx10^(6) xx150`
`sigma=828.6 km^(-2)`
