Vedclass · Answer

(C) The electric field $E$ exerts a force $F = qE$ on a charged particle. For an electron,the charge $q = -e$,so the force $F = -eE$ acts in the direction opposite to the electric field lines.Since the electron enters the field with its velocity in the direction of the electric lines of force,the force acting on it is directed opposite to its velocity.This force acts as a retarding force,causing the electron to decelerate.Therefore,the velocity of the electron will decrease.

An electron enters an electric field with its velocity in the direction of the electric lines of force. Then:
