Two parallel plates A and B of infinite extent are spaced 1 cm apart. a steam of electrons is projected at a velocity corresponding to an accelerating voltage of 2kV into space betn the plates through a hole in plate A at an angle of 30 deg to it. find the value and polarity of the potential reqd betn A and B such that electrons just graze B.
