The electrons in the beam of a television tube have an energy of13 keV. The tube is oriented so that the electrons movehorizontally from north to south. The vertical component of theEarth's magnetic field at the location of the television has amagnitude of 42.0 ?T and is pointing down.
a) In which direction does the force on the electrons act (enter Nfor north, S for South, E for East, or W forWest)? Â
Neglect a possible horizontal component of the magnetic field.
b) What is the magnitude of the acceleration due to the verticalcomponent of the Earth's magnetic field of an electron in thebeam?
c) If the inclination of the earth's magnetic field near the TVis 51deg, calculate the magnitude of the force on the electrons dueto the horizontal component of the Earth's magnetic field.
