Dear student

A geo-stationary satellite is satellite with the orbital period
same as the period of earth
The time period of geostationary satellite is given by
T=2πRR+h3gR+h=gR2T24π21/3where T=24 hours=86400 s, g=9
8 m/s2, R=6 37×106 mso R+h=9 8×6
37×1062×8640024×3 1421/3R+h=42
22×106 mh=42 22-6 37×106 mh=35
85×106 m
