56c) Consider a beam of electrons passing through a region with crossed electric and magnetic fields. Suppose the electric field strength is 7.6E4 V/m (7.6 times 10 to the 4th) and the magnetic field strength is 9.3E-2 T (9.3 times 10 to the minus 2). The beam is not deflected as it passes through these fields. What is the speed (in m/s) of the electrons?
