An electron in a television tube moves with a speed of 5.74 107 m/s, in a direction perpendicular to the Earth's field, which has a strength of 5.00 10-5 T. (a) What strength electric field must be applied perpendicular to the Earth's field to make the electron move in a straight line? kV/m (b) If this is done between plates separated by 1.35 cm, what is the voltage applied? (Note that TVs are usually surrounded by a ferromagnetic material to shield against external magnetic fields and avoid the need for such a correction.)
