Geostationary satellite completes its one revolution around the earth in

Result
Your answer: —  Â·  Correct: B
Explanation

A geostationary satellite is a specific type of geosynchronous satellite that orbits in the Earth's equatorial plane. Its primary characteristic is that its orbital period exactly matches the Earth's rotation period [2]. While the precise sidereal rotation period of the Earth is approximately 23 hours, 56 minutes, and 4 seconds, it is conventionally referred to as 24 hours in general scientific and communication contexts [2]. This synchronization allows the satellite to remain fixed relative to a specific point on the Earth's surface, making it ideal for telecommunications and weather monitoring [2]. By completing one revolution in 24 hours (one day), the satellite's angular velocity matches the Earth's rotation, ensuring it appears stationary to an observer on the ground.
