Question

The time period of a geo-stationary satellite is

• A. $24\mathrm{hrs}$
• B. $6\mathrm{hrs}$
• C. $365days$
• D. none of these

Answer 1

The correct option is A

$24\mathrm{hrs}$

1. A geostationary satellite is an earth-orbiting satellite that rotates in the same direction as the earth.
2. It is stationed at an altitude of approximately $35,800kilometers$directly over the equator (west to east).
3. One orbit takes $24hours$ at this altitude, the same amount of time it takes the earth to rotate once on its axis.
4. The word geostationary refers to a satellite that appears practically stationary in the sky when observed from the ground.

Hence option A is correct, the time period of a geostationary satellite is $24hours$.
