What uniform magnetic field, applied perpendicular to a beam of electrons moving at 6.75x106 m/s In Figure below, an electron accelerated from rest during potential difference V1=1.36 kV enters the gap among two parallel plates having separation d = 15.8 mm and potential difference V 2= 158 V. The lower plate is at the lower potential. Neglect fringing and suppose that the electron's velocity vector is perpendicular to the electric field vector among the plates. In unit-vector notation, what uniform magnetic field allows the electron to travel in a straight line in the gap?, is required to make the electrons travel in a circular arc of radius 0.282 m?
