Question
In Fig. 28-31, an electron accelerated from rest through potential difference V1=1.24 kV enters the gap between two parallel plates having separation d = 18.9 mm and potential difference V2= 63.6 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?

Explanation / Answer
you didnt give any figure here with some assumpotions i get B =(0i+0j -0.161k)mT
