Electrons in the beam of a television tube have an energy of 12 keV. The tube is oriented so that the electrons move horizontally from the magnetic south to the magnetic north. Does the vertical component of the Earth's magnetic field point down and have a 55 μT module. (a) In which direction will the beam be diverted? (b) Calculate the acceleration of an electron given due to the magnetic field, (c) How far will the beam be diverted when moving 20 cm through the television tube? Answers: a) east; b) 6.28 * 10^14 m/s²; c) 2.98 mm
