electron in a cathode ray tube has a kinetic energy of 102 eV and moves in a direction perpendicular to Earth’s magnetic field (about 5.0x10-5 T). a. What strength electric field must be applied perpendicular to the Earth’s magnetic field to make the electron move in a straight line? b. If this is done between plates separated by 1.00 cm, what is the voltage applied to the plates?
