Question

If two objects have an overall gravity of 360N, what will the gravity be if the distance is cut into half of its original value?

Answer 1

I'm not sure what you mean by "overall gravity".

If you're talking about the gravitational force of attraction between the two bodies, and you move them together so that they're half as far apart as they used to be, then the gravitational force between them will be 4 times as strong as it was originally.

The force of attraction changes from 360N to 1,440N .
