Solution

The correct option is B Orbit the earth every $24$ hours
There are three essential conditions for geosynchronous satellites :
(i) The period of revolution around the earth should be same as of earth i.e. $24$ hours.
(ii) Its sense of rotation should be same as of earth.
(iii) It should revolve in an orbit concentric and coplanar with the equatorial plane.

A geosynchronous satellite is a satellite that orbits the earth with an orbital period of 24 hours, thus matching the period of the earth's rotational motion. A special class of geosynchronous satellites is a geostationary satellite. A geostationary satellite orbits the earth in 24 hours along an orbital path that is parallel to an imaginary plane drawn through the Earth's equator. Such a satellite appears permanently fixed above the same location on the Earth. If a geostationary satellite wishes to orbit the earth in 24 hours (86400 s), then how high above the earth's surface must it be located? (Given: $M_{e a r t h} = 5.98 \times 10^{24} k g, R_{e a r t h} = 6.37 \times 10^{6} m$ )
