a. In a synchrotron, electrons move in an approximately circular orbit of
length l = 240 m. During the acceleration cycle, there are approximately
n = 1011 electrons in orbit, their speed is almost equal to the speed of light.
What is the current equal to?
b. Determine the current generated by an electron moving in an orbit of radius
r = 0.5⋅10−10 m in a hydrogen atom.
