Height of geostationary satellite is

Options

  1. A(16000 ~km )
  2. B(22000 ~km )
  3. C(28000 ~km )
  4. D(36000 ~km )

Correct answer

D. (36000 ~km )

Step-by-step solution

The principle of the geostationary satellite is its period of rotation is the same as that of the earth. ( -G M m r^2 +m ^2 r=0 ) i.e. ( G M (R+h)^2 = ( 2 T )^2(R+h) ) (h ) works out to (36000 ~km ).
