An electron in the beam of a TV picture tube is accelerated by a potential difference of 2.04 kV. Then it passes through a region of transverse magnetic field, where it moves in a circular arc with a radius of 0.184 meter.
Determine what is the magnitude of the field? Use 9.11 × 10-31 kilogram for the mass of an electron and 1.60 ×10-19 C for the magnitude of the charge on an electron.
