Chapter 28, Problem 009
In the figure, an electron accelerated from rest through potential
difference V₁=1.06 kV enters the gap between two parallel plates having
separation d = 24.5 mm and potential difference V₂= 99.1 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?
