Q. A satellite moves in a circular orbit around the earth. the radius of this orbit is one half that of moons orbit. find the time in which the satellite completes one revolution. Give the solution also

Q.

Assertion : The time period of geostationary satellite is 24 hours.

Reason : Geostationary satellite must have same time period as time taken by the earth to complete one revolution about its axis.
