A beam of electrons is accelerated through a potential difference of 12.0 kV before entering a velocity selector. If the B-field of the velocity selector is perpendicular to the velocity and has a value of 0.02 T, what value of the E-field is required (in the magnetic field region) if the particles are to be undeflected?
