An electron in a TV CRT moves with a speed of 6.0 x 10ʻm/s, in a direction perpendicular to Earth's field, which has a strength of 5.0× 10¬³T. (a) What strength electric field must be applied perpendicular to the Earth's field to make the electron moves in a straight line? (b) If this is done between plates separated by 1.00 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.)
