14. (7 pts) An electron in an old-style television picture tube moves toward the front of...
The picture tube in an old black-and-white television uses magnetic deflection coils rather than electric deflection plates. Suppose an electron beam is accelerated through a 51.0-kV potential difference and then through a region of uniform magnetic field 1.00 cm wide. The screen is located 10.9 cm from the center of the coils and is 50.6 cm wide. When the field is turned off, the electron beam hits the center of the screen. Ignoring relativistic corrections, what field magnitude is necessary...
An electron moves at 3.75 Mm/s in the plane XY at 60 angle with the X axis and at 30 angle with the Y axis. A Magnetic field of 0.85 T in a positive direction of the Y axis Find the magnetic force acting over the electron
1. An electron moves in a circular path in the magnetic field of an electromagnet. The plune of the electron's Sicular path is parallel to the smooth vole faces of the electromagnet. In the region where the electron is moving the magnetic field is uniform and has magnitude 0,50 T. The electron moves with a speed of 1.5 x 10 m/s. a. If someone could observe the electron from the north pole of the electromagnet, would the electron inove clockwise...
