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?
Use 9.11×10−31 kg for the mass of an electron and 1.60×10−19 C for the magnitude of the charge on an electron.

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...
