When a charged particle is in an electric field, it experience a force and hence accelerates. If the electric field is in the direction of motion, the particle continues to move along a straight line but simply moves faster.
If the electric field is perpendicular to the initial direction of motion, the particle follows a parabolic trajectory.
Thus, in a uniform electric field, the trajectory of a charged particle is either a straight line or a parabola.
