Q1)
A satellite weighing ( 700 Ib ) on the surface of
the Earth. Calculate the Earth's gravitational force for
this satellite when it is positioned at a distance of
( 36000 km ) from the surface of the Earth, where its
rotation speed around the Earth is equal to the speed
of the Earth's rotation around itself.
- Earth mass ( Me ) = 5.97 × 102ª kg.
- Radius of the Earth ( Re ) = 6371 km.
36000 km
