In the electron gun of a TV picture tube the electrons (charge -e, mass m) are accelerated
Question:
V. After leaving the electron gun, the electron beam travels a distance D to the screen; in this region there is a transverse magnetic field of magnitude B and no electric field.
(a) Sketch the path of the electron beam in the tube.
(b) Show that the approximate deflection of the beam due to this magnetic field is
(c) Evaluate this expression for V = 750 V, D = 50 cm, and B = 5.0 X 10-5 T (comparable to the earth's field). Is this deflection significant?
