A geo-stationary satellite is orbiting the earth at height of 6 R above the surface of the earth, R being the radius of earth. The time period of another satellite at a height of 2.5 R from the surface of the earth is

Options

  1. A10 h
  2. B6 / 2 h
  3. C6 h
  4. D6 2 h

Correct answer

D. 6 2 h

Step-by-step solution

Distance of the satellite from the centre are 7 R and 3.5 R respectively. gathered T₂ T₁ = ( R₂ R₁ )^ 3 / 2 T₂=24 [ 3.5 R 7 R ]^ 3 / 2 =6 2 ~h gathered
