Question

The electron that flies in the tube has energy of 12 keV. The cathode-ray tube is oriented so that the electrons move in a horizontal direction from the south to the north. Earth's magnetic field component B = 5.5 * 10-5T is facing downwards. In what direction will the electron beam be tilted? How big is the electron beam deflection x when the electrons in the tube have flown 20 cm?
