|
|
it orbits the Earth in the direction follow the direction of Earth’s rotation
|
|
|
Its orbital period is equal to the period of Earth’s rotation
|
|
|
Its orbit is concentric to the equator
|
|
|
It rotates on its axis with a period same as the period of Earth’s rotation
|
Detailed explanation-1: -It pretends to be stationary with respect to the Earth but if we talk about the Angular Speeds of both the Earth and the Geostationary satellite, they are different. Hence, the correct option is B. Hope that this answer helps you.
Detailed explanation-2: -The satellite which appears stationary relative to earth is called the geostationary satellite . it revolves around the earth in the west-east direction with the same angular velocity as done by the earth about its own axis in the west-east direction .
Detailed explanation-3: -Necessary conditions for a geostationary satellite: It should revolve in an orbit concentric and coplanar with the equatorial plane of the earth. Thus option 1 is correct. Its direction of rotation is same as that of the earth i.e., from west to east. Thus option 2 is incorrect.
Detailed explanation-4: -Satellites in geostationary orbit (GEO) circle Earth above the equator from west to east following Earth’s rotation – taking 23 hours 56 minutes and 4 seconds – by travelling at exactly the same rate as Earth. This makes satellites in GEO appear to be ‘stationary’ over a fixed position.
Detailed explanation-5: -The time period of revolution of a geostationary satellite around earth is same as that rotation of earth about its own axis i.e. 24 hours.
Detailed explanation-6: -Solution: The height of Geostationary satellite is 6R from the surface of earth and 7R from the centre of earth.
