A) \[800\text{ }m\]
B) \[700\text{ }m\]
C) \[600\text{ }m\]
D) \[500\text{ }m\]
Correct Answer: A
Solution :
[a] \[h=100m,\,\,d\propto \sqrt{h}\] To triple coverage range, d is to be increased to 3d \[\Rightarrow \,\,\,\,\,\,\,\,\,h'=9h=900m\] Increase in height \[=h'-h=800m\]You need to login to perform this action.
