Task 30368.

The flat capacitor between the plates is an electric field strength of E = 100 V / m, it is placed in a magnetic field so that the field lines are perpendicular fields. What should be in the induction of the magnetic field to the electron with initial energy T = 4 keV, had entered with a space between the capacitor plates perpendicular to the magnetic field lines, not change direction of speed?
