An electron in a TV CRT moves with a speed of 6.25 × 107 m/s, in a direction perpendicular to the Earth's field, which has a strength of 5.00 x 10-5 T. (a) What strength electric field (in kV/m) 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 1.20 cm, what is the voltage applied (in V)? (Note that TVs are usually surrounded by a ferromagnetic material to shield against external magnetic fields and avoid the need for such a correction.) V
