The microwaves in a microwave oven are produced in a special tube called a magnetron. The electrons orbit the magnetic field at 2.4 GHz, and as they do so they emit 2.4 GHz electromagnetic waves.
What is the magnetic field strength?
If the maximum diameter of the electron orbit before the electron hits the wall of the tube is 2.5 cm, what is the maximum electron kinetic energy?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf Ξ΅. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 Ο, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
