ATV tower has a height of 100m. How much population is covered by TV broadcast. If the average population density around the tower is `1000 km^(-2)` ? (radius of earth =`6.4xx10^(6)m`)

A

`4` lakh

B

`4` billion

C

`40,000`

D

`40` lakh

Text Solution

Verified by Experts

The correct Answer is:
D
`d=sqrt(2hR)`
Population covered `=pid^(2)` x Population density
`=pixx2hR` x Population density
`=(3.14xx2xx100xx6.37xx10^(6)xx1000)/(1000xx1000)`
`4xx10^(6)`
`10` lakh.
