APFIVE Undeflected Electron Beam in Crossed Fields
A beam of electrons travels between two parallel plates with a potential difference that creates an electric field E perpendicular to the beam. What magnetic field direction and magnitude B would allow the electrons to pass through undeflected?
A
B = v/E, perpendicular to both E and v
B
B = E/v, perpendicular to both E and v
C
B = E/v, parallel to E
D
B = Ev, perpendicular to both E and v
