In а setup similаr tо J. J. Thоmsоn’s experiment, аn electron beam passes through a pair of parallel deflection plates of length 10.0 cm, producing a uniform electric field of 1000 V/m. When only the electric field is applied, the electron beam is deflected by an angle of 30°. When a uniform magnetic field of 8.8×10−4 T is applied perpendicular to the electric field, the beam shows no deflection. (a) Determine the initial velocity of the electron.(b) Calculate the charge-to-mass ratio of the electron.
