Question:
The orbital period of a geostationary satellite is
The orbital period of a geostationary satellite is
Show Hint
A geostationary satellite must have the same angular velocity as Earth, so its time period is always \(24\) hours.
Updated On: Jun 25, 2026
- \(2\text{ h}\)
- \(5\text{ h}\)
- \(24\text{ h}\)
- \(12\text{ h}\)

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understand geostationary satellites.
A geostationary satellite revolves around the Earth in such a way that it appears stationary relative to an observer on Earth.
For this to happen, the satellite must complete one revolution in the same time taken by the Earth to rotate once about its axis.
Step 2: Use Earth's rotational period.
The Earth completes one rotation in approximately \[ 24\text{ hours} \] Therefore, the orbital period of a geostationary satellite must also be \[ 24\text{ hours} \]
Step 3: Final conclusion.
Hence, \[ \boxed{24\text{ h}} \]
