A TV tower has a height (160 ~m ). Its coverage range is nearly (Earth's radius, (R_e=6400 ~km ))
Options
- A(45255 ~m )
- B(55265 ~m )
- C(452.55 ~km )
- D(552.65 ~m )
Correct answer
A. (45255 ~m )
Step-by-step solution
Given, height of a TV tower, (h=160 ~m ) Radius of earth, (R=6400 ~km =6.4 10^6 ~m ) Coverage range of TV tower is given by (d= 2 R h = 2 6.4 10^6 160 =45254.8=45255 ~m )
