Light striking a metal plate can eject electrons from the plate's surface (this is called the photoelectric effect). Imagine that we place the plate in a vacuum and set up an electric field in the plate's vicinity that is uniform in magnitude and direction such that the electric field vector E at any point near the plate has a magnitude of 1000 N/C and points directly away from the plate, perpendicular to its surface. Electrons ejected with the photoelectric effect will have initial kinetic energies of no more than about 3 eV, where 1 eV = 1.6 x 10^-19 J. Roughly estimate the maximum distance that an ejected electron can obtain from the plate under these circumstances. (Hint: Consider an analogy to the behaviour of a thrown ball in a uniform gravitational field.)
