The orbit of geostationary satelite is circular , the time period of satellite depend 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

A. (i) only
B. (i) and (ii)
C. (i) , (ii) and (iii)
D. (ii), (iii)and (iv)

Answer

D

Explanation

The time period of a geo- stationary satellite ,
Talpha `(1)/(M^(1/2)) alpha (R+h)^(3/2)`
where,
R- Radius of the orbit
h- Height of the satellite from the earth's surface .
