Geostationary satellite completes one rotation around the earth in_______________?
Correct answer: D. 24 hours
- A. 3 hours
- B. 6 hours
- C. 12 hours
- D. 24 hours
Explanation
A geostationary satellite must have the same angular speed as Earth's rotation, completing one revolution in Earth's rotational period. Earth's rotation period is approximately 24 hours, so the satellite also takes 24 hours for one orbit. The likely mistake is choosing 12 hours, which corresponds to half a daily rotation rather than one complete rotation.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
