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?
In a cathode-ray tube, a beam of electrons (the cathode ray) is deflected in a region of electric field on its way to a fluorescent screen, as shown in the figure. Consider the parallel-plate arrangement in the figure, and assume that the electric field E = 400 N/C is uniform between the plates and that E = 0outside the plates. The beam of electrons is injected horizontally with velocity v0 = 5.0 × 106 m/s. If the width of the...

A cathode ray tube (CRT) is used to display images in some televisions and computer monitors by accelerating electrons from the cathode toward the anode, which is at a higher potential than the cathode. If the potential difference between the cathode and anode is 25 kV, at what speed do the electrons move as they reach the anode? Express your answer in scientific notation. (in m/s) (Hint: energy is conserved)
An electron in the beam of a TV picture tube is accelerated by a potential difference of 1.92 kV . Then it passes through a region of transverse magnetic field, where it moves in a circular arc with a radius of 0.186 m . What is the magnitude of the field?
