2. An electron in a television picture moves toward the front of the tube with a speed of 8x 106 m/s along the x-axis. Surrounding the neck of the tube are coils of wire that create a magnetic field of magnitude 0.025 T, directed at an angle of 60° to the x-axis and lying in the xy plane. (a) Calculate the magnitude of the force on the electron and the radius of the path. (b) Find the angular speed and hence the period of motion around the neck of the tube. (c) What is the magnitude of the electrical potential difference that can accelerate the electron through the magnetic field?
