At a particular station, the TV transmission tower has a height of 100 m. To triple its coverage range, height of the tower should be increased to
Text Solution
Verified by ExpertsThe correct answer is:
D
Let d be range
d 2 = h 2 +2Rh
as R >>>> h then
.... (1)
Now, if coverage is to be increased 3 times
....(2)
Divide 2 and 1 
If h = 100 m then tower of height 900 m is required
