Given
Mass of satellite 1 = 5.3 * 10¹²kg
Mass of satellite 2 = 3.5 * 10⁸kg
Distance between them = 1,800 m
Required
Gravitational Force between them.
The gravitational force between them is calculated as thus;

Where G = Gravitational Constant




Substituting these values in the above formula;
becomes





---- Approximated
Hence the gravitational force between them is
