Detailed explanation-1: -Assertion : The time period of geostationary satellite is 24 hours. Reason : Geostationary satellite must have same time period as time taken by the earth to complete one revolution about its axis.
Detailed explanation-2: -As the geostationary satellite is established in an orbit in the plane of the equator at a particular place, so it move in the same sense as the earth and hence its time period of revolution is equal to 24 hours, which is equal to time period of revolution of earth about its axis.
Detailed explanation-3: -The time period of a geostationary satellite is 24 h, at a height 6R (Reis radius of earth) from surface of earth.
Detailed explanation-4: -Definition: Geosynchronous satellite is placed in the geosynchronous orbit with an orbital period matching the Earth’s rotation period. These satellites take 24 hours to complete one rotation around the earth.
