Time taken by a geostationary satellite to complete one rotation around the Earth is
Correct answer: B. 1 day
- A. 1 year
- B. 1 day
- C. 1 hr
- D. 84 min
Explanation
A geostationary satellite orbits the Earth once every 24 hours, which is the same time it takes for the Earth to complete one rotation. This ensures that the satellite remains above the same point on the Earth's surface.

About Satellite Motion and Orbital Velocity
Satellite motion uses gravitational force as the centripetal force required for circular orbit, giving relationships among orbital radius, period and orbital velocity. Questions cover geostationary conditions and weightlessness, while distinguishing orbital velocity, escape velocity and the satellite's tangential speed.
