Is it possible for the gravitational force between two 50-kg objects to be less than the gravitational force between a 59-kg object and a 5-kg object? explain.

OF COURSE !  

The gravitational force between two objects doesn't ONLY depend on the product of their masses.  It also depends on the distance between them.

I'm not even going to work out the numbers for my example.  I'm just going to state without proof that at the top of the 2nd frame, the gravitational force between you and your bowling ball is greater than the gravitational force between you and the whole darn Andromeda galaxy !  My reasoning is based on the fact that your bowling ball is maybe 1 foot from your center of mass, whereas the Andromeda galaxy is more like 2.5 million light years from it.  That right there is going to give your bowling ball a big advantage when it comes to gravity !
