Two identical satellites and are launched in equatorial circular orbits around Earth with the same period of revolution of 4.8 hours. Satellite rotates west to east (with Earth's rotation) while satellite rotates east to west (against Earth's rotation).
On a particular day, both satellites were seen directly overhead by an observer standing at point on Earth’s equator. How long (in hours) will it be until both satellites are seen directly overhead again from the same point
