There are no preferences, just calculation of the trajectory is my task.
Alright, so I inserted the B formula into the Fm formula and got Fm=1.6*10^-20/R.
Divided it by the mass of the electron and got the acceleration.
Did the integral of that and got v=1,76*10^10*ln|R|+C (which I assume is 0...
B equals 50*10^-7 T (at first instance)
Fm equals 8*10^-20 N (at first instance)
I know Fm is perpendicular to the velocity, and I know the estimation of the trajectory (somewhat similar to the curve y=lnx).
Since I think vertical velocity will be constant, only changing the x component, I...
