John and Tou take their toys down to a nearby pond to play. John has a toy boat made from wood. He places the wooden boat on the pond and it floats. Tau, being a checky little boy, wants to make John's
wooden boat sink. So he attaches a piece of lead on one end of the string, and ties the other loose end onto
John's boat and gently places the lead into the water. Determine the smallest amount of lead (mass) that
will be enough to sink John's boat, assuming the specific gravity of wood is 0.5 and the density of the
pond water is equal to the density of pure water

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.
