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?
(i) only
(i) and (ii)
(i), (ii) and (iii)
(ii), (iii) and (iv)
Solution
Time period of satellite $T \propto \frac{1}{M^{1 / 2}}$, where $M$ is mass of earth. $\propto(R+h)^{3 / 2}$ where $R$ is radius of the orbit, $h$ is the height of satellite from the earth's surface.
