Her source of electrons will be a certain vacuum tube, in which electrons evaporate from a hot cathode at a slow, steady rate and accelerate from rest through a potential difference of 53.5 v. after being accelerated, they travel through a field-free and evacuated region before they pass through the double slits and fall on a screen to produce an interference pattern. to ensure that only one electron at a time is passing through the slits, she wants the electrons to be separated in space by d = 1.00 cm (perpendicular to the barrier containing the slits) as they approach the slit. she asks you to determine the maximum value for the beam current (in a) that will assure that only one electron at a time passes through the slits.
