An electron in a TV CRT moves with a speed of 6.00×10^7 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 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.)
