4. (10 pts) An electron in a cathode-ray beam passes between 2.5-cm-long parallel-plate elec- trodes that are 5.0 mm apart. A 2.0 mT, 2.5-cm-wide magnetic field is perpendicular to the electric field between the plates. The electron passes through the electrodes without be- ing deflected if the potential difference between the plates is 400 V. What is the electron's speed?...
