A T.V. Tower has a height 100m. In order to triple its coverage range, the height of tower to be increased is `axx10^(2)`m. What is the integer value of a ?

Text Solution

Verified by Experts

`d'=sqrt(2h'R)=3d=3sqrt(2 hR)`
or `h'=9h=9xx100=900m`
Increase in height of tower`=900-100=800`
`=a xx 10^(2)`
a=8
