A T.V. tower has a height 150m. What is ...

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

`82.6km^(-2)`

B

`800-6 km^(-2)`

C

`828.6 km^(-2)`

D

`876-6km^(-2)`

Text Solution

Verified by Experts

Population covered`=pxx pi d^(2)=p xx pi 2 hR`
So `50xx10^(5)=pxx(22)/(7)xx2xx150xx6.4xx10^(6)`
On solving. `p=828.6 km^(-2)`
