One complete of geo-stationary satellite orbit around the earth takes approximately
Correct answer: B. 24 hours
- A. 1 hour
- B. 24 hours
- C. 120 hours
- D. 365 hours
Explanation
A geo-stationary satellite completes an orbit around the Earth in 24 hours, which allows it to remain fixed relative to a point on the Earth's surface. This is because it orbits at the same rate that the Earth rotates. The other options (1 hour, 120 hours, and 365 hours) do not align with the Earth's 24-hour rotational period, making them incorrect.

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.
