Two large conducting parallel plates A and B are separated by 2.4 m.A uniform field of ,in the positive x-direction,is produced by charges on the plates.The center plane at
m is an equipotential surface on which
.An electron is projected from
,with an initial velocity of
perpendicular to the plates in the positive x-direction,as shown in the figure.What is the kinetic energy of the electron as it reaches plate A?
