Avery massive object a and a less massive object b move toward each other under the influence of gravity. which force, if either, is greater

Both are equal.

Explanation:

As per the theory of gravitational force, when two objects will be thrown from same height but of different masses, both will reach the ground at same time.

The force of gravity will act same on both objects.

Simple experiments were done by Sir Isaac Newton to reach out to reach out to this conclusion. Two objects were made to fall free under the influence of gravity, neglecting every other small forces, it was observed irrespective of different masses both reaches the ground at same time.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
