Question

A satellite close to the earth is in orbit above the equator with a period of rotation of `1.5` hours. If it is above a point `P` on the equtor at some time, it will be above `P` again after time ...........

Answer 1

Correct Answer - `1.6` hours if it is rotating from west to east, `24//17` hours if it is rotating from east to west
`omega_(rel)=omega-omega_(earth)`
When satellite orbiting from east to west.
`omega_(rel)=omega+omega_(earth)`
`(2pi)/T=(2pi)/(3//2)-(2pi)/24impliesT=24/17 H`
