Reference: Suppose two satellites that orbit the earth passes close to each other. Also, for a moment they are 100 m apart. Furthermore, the masses of the satellites are 300 kg and 20 kg. So, calculate the magnitude of the force of gravity between these satellites? (4.0 x 10 ^-11 N)

Hi everyone, I want to know if there is a specific value or equation that would tell me if the satellites would collide. If I know the mass, distance apart and gravity can I definitively say that they will or will not collide, do I need an equation to prove it, is there a minimum value for gravity to make this true?

Any help would be greatly appreciated, thank you!
