    An electron in a trajectory motion between the center of two plates

    Homework Statement An electron with an initial velocity of 5.6x107 m/s in the x-direction moves along a trajectory that takes it directly between the center of two 20 cm x 20 cm plates separated by 1 cm. The plates are connected to a high voltage power supply so that the potential difference...
