2. Two charges are located along the x-axis. One has a charge of 6.4 UC, and the second has a charge of -3.2 UC. If the electrical potential energy asso-
ciated with the pair of charges is -4.1 x 10-, what is the distance
between the charges?

magnitude and direction

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.
