In a synchrotron, electrons are accelerated to speeds close to the speed of light v≈c≈3×108 m/s Suppose that in a synchrotron, 100 billion (1011) electrons move in a circular orbit of circumference L=300 m . Determine the electric current in Amps due the flow of electrons in the synchrotron.( You may assume that the electrons are homogeneously distributed over the circular orbit.)
