Final answer:
The motion of a proton and an electron in a uniform electric field is influenced by the force and acceleration experienced by each particle. The magnitude of the force on both particles is the same because they have the same charge, but the directions of the forces are opposite. The acceleration of the electron is greater than that of the proton due to its smaller mass.
