A5.3 1012 kg satellite is 1,800 m from another satellite that has a mass of 3.5 x 108 kg. What is the gravitational force between the satellites?
3.82 x 104N
6.87 x 107 N
5.72 x 1014 N
0 1.03 x 1018 N

Explanation:

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

the answer will be d
