Quizplus · Accepted Answer

Since the electric field is in the direction of the force on the charged particle, we know that electrons, being negatively charged, will be accelerated in the opposite direction of the electric field lines. Protons, being positively charged, have a force in the same direction as the electric field lines. Since acceleration is directly proportional to force, the electron will experience a greater acceleration than the proton. Therefore, choice A is the best answer.
