The orbit of geo-stationary satellite is circular, the time period of satellite depends on (i) mass of the satellite (ii) mass of the earth (iii) radius of the orbit (iv) height of the satellite from the surface of earth Which of the following is correct?

Options

  1. A(i) only
  2. B(i) and (ii)
  3. C(i), (ii) and (iii)
  4. D(ii), (iii) and (iv)

Correct answer

D. (ii), (iii) and (iv)

Step-by-step solution

Time period of satellite T∝1M1/2T \propto \frac{1}{M^{1 / 2}}, where MM is mass of earth. ∝(R+h)3/2\propto(R+h)^{3 / 2} where RR is radius of the orbit, hh is the height of satellite from the earth's surface.
