Question
In the figure, an electron accelerated from rest through potential difference V1-0.834 kV enters the gap between two parallel plates
having separation d = 27.3 mm and potential difference V2= 183 V. The lower plate is at the lower potential. Neglect fringing and
assume that the electron's velocity vector is perpendicular to the electric field vector between the plates. In unit-vector notation, what
uniform magnetic field allows the electron to travel in a straight line in the gap?
