Question
The microwaves in a microwave oven are produced in a special tube called a magnetron. The electrons orbit in a magnetic field of 9.3×10−2 T at a frequency of 2.6 GHz, and as they do so they emit 2.6 GHz electromagnetic waves.
If the maximum diameter of the electron orbit before the electron hits the wall of the tube is 2.3 cm, what is the maximum velocity the electrons may have?

They make a circle each 1/2.6E9 seconds, so velocity
velocity= distance/time= PI*.023*/2.6E9
velocity= distance/time= PI*.023*/2.6E9
