A deuteron (the nucleus of an isotope of hydrogen) has a mass of 3.34×10−27 kg and a charge of 1.60×10−19 C. The deuteron travels in a circular path with a radius of 7.20 mm in a magnetic field with a magnitude of 2.50 T. a) Find the speed of the deuteron. (Express answer in m/s)
b) Find the time required for it to make 1/2 of a revolution. (Express answer in s)
c) Through what potential difference would the deuteron have to be accelerated to acquire this speed? (Express answer in volts)

seeing the graph would

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.
