An electrical short cuts off all power to a submersible diving vehicle when it is a distance of 26 mm below the surface of the ocean. The crew must push out a hatch of area 0.80 m2m2 and weight 320 NN to escape.

Part A If the pressure inside is 1.0 atmatm, what downward force must they exert on the hatch to open it

are there answer choices to this question? this seems like a question where you have options to choose from.

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.
