A beam of electrons whose kinetic energy is K emerges from a thin-foil window at the end of an accelerator tube. A metal plate at distance d from this window is perpendicular to the direction of the emerging beam (see figure). We can prevent the beam from hitting the plate if we apply a uniform magnetic field such that B≥e 2 d 2 2 mK in which m and e are the electron mass and charge. How should B be oriented?
