Question
Which of the following are true?
- A polar satellite goes around the earth’s pole in north- south direction.
- A geostationary satellite goes around the earth in east-west direction.
- A geostationary satellite goes around the earth in west-east direction.
- A polar satellite goes around the earth in east-west direction.
Solution
a and c
Explanation:
A satellite which appears stationary relative to the earth is called a geostationary or geosynchronous satellite or communication satellite.
A geostationary satellite revolves around the earth with the same angular velocity and in the same sense as done by the earth about its own axis, i.e. west-east direction.
A polar satellite revolves around the earth’s pole in a north-south direction. It is independent of the earth’s rotation.

As you have learnt in the text, a geostationary satellite orbits the earth at a height of nearly 36,000 km from the surface of the earth. What is the potential due to earth’s gravity at the site of this satellite? (Take the potential energy at infinity to be zero). Mass of the earth = 6.0 × 1024 kg, radius = 6400 km

What is the angle between the equatorial plane and the orbital plane of polar satellite?
What is the angle between the equatorial plane and the orbital plane of geostationary satellite?
Mean solar day is the time interval between two successive noon when sun passes through zenith point (meridian). Sidereal day is the time interval between two successive transit of a distant star through the zenith point (meridian). By drawing appropriate diagram showing earth’s spin and orbital motion, show that mean solar day is four minutes longer than the sidereal day. In other words, distant stars would rise 4 minutes early every successive day.
A satellite is to be placed in equatorial geostationary orbit around earth for communication.
- Calculate height of such a satellite.
- Find out the minimum number of satellites that are needed to cover entire earth so that at least one satellites is visible from any point on the equator.
