Now here we look at the motion of particle, basically, in, we look at the motion of particle in a magnetic field, right? so what's happening is the following, you have, basically you have a plate, right? prudia plates and there's some electric field in between it, right? so the plates, you know, the potential difference between the plate is decav equals 200 volts, and then the, some ions with some mass with some charge, kill, and accelerate through this, and enters a magnetic field like this, uniform magnetic field like this.

So magnet field is given certain strengths, right? and you asked, so the particles is accelerated by this potential and enters this uniform, this magnet field, of course, is going to execute a, you know, this kind of circular motion, right? so we asked actually the speed, when it enters here, right? the speed ends here, of course, it can be cacked using the energy conservation.

So basically, mv squared over two, that's kinetic energy, and this kinetic energy comes from the work down by the electric field...
