A simple and common technique for accelerating electrons is shown in the figure, where there is a uniform electric field between two plates. Electrons are released, usually from a hot filament, near the negative plate, and there is a small hole in the positive plate that allows the electrons to continue moving. Calculate the horizontal component of the acceleration if the field strength is 2.6*10^4 N/C. Express your answer in m/s^2, and assume the electric field is pointed in the negative direction.
