Each of the electrons in the beam of a television tube has a kinetic energy of 12.6 keV. The tube is oriented so that the electrons move horizontally from geomagnetic south to geomagnetic north. The vertical component of Earth's magnetic field points down and has a magnitude of 55.0 μT. (b) What is the acceleration of a single electron due to the magnetic field? m/s2 (c) How far will the beam deflect in moving 16.0 cm through the television tube?
