Chapter 26, Problem 23(choose chapter or problem)
In a microwave oven, electrons describe circular motion in a magnetic field within a special tube called a magnetron; as youll learn in Chapter 29, the electrons motion results in the production of micowaves. (a) If the electrons circle at a frequency of 2.45 GHz, whats the magnetic field strength? (b) If the magnetron can accommodate electron orbits with maximum diameter 2.72 mm, whats the electrons energy in eV?
