Question

two plates are parallel distance between 0.02m first plate is (R,S) and other plate is (P,Q) .plate (R.S) on the potential difference is +100 with respect to (P.Q) and the slits A and B on the plate (R.S) seperated by 0.05m.A continuiting beam containing electrons and directly the angle is 60? FIND: the kinetic energy of electrons which just reach.
