A problem of practical interest is to make a beam of electrons turn at 90° corner. This can be done with the parallel plates shown in figure. An electron with kinetic energy 8.0 × 10-17J enters through a small hole in the bottom plate. The strength of electric field that is needed if the electron is to emerge from an exit hole 1.0cm away from the entrance hole, traveling at right angles to its original direction is _______ ×105N/ C.
