On a separate sheet of paper, make a claim in which you mathematically state the rule of balance - that is, the rule that one must use to determine if two weights placed on opposite sides of the fulcrum will balance each other. Then use one result from Q#1-4 and one result from Q#6-9 as evidence in support of your claim. For each question you select to discuss, thoroughly explain with solid reasoning how the data serve as evidence in support of your claim.

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.
