How Do Charged Particles Move in Electric Fields?

TL;DR

Charged particles moving perpendicular to electric fields follow parabolic trajectories due to the electric force acting in the vertical direction. While maintaining constant velocity in the horizontal direction, these particles experience acceleration due to the unbalanced electric force in the vertical direction. The time taken to traverse distances in both dimensions is equal, simplifying velocity and displacement calculations.
