suppose that a particle accelerator is used to move two beams of particles in opposite directions. in a particular region, electrons move to the right at 4910 m/s4910 m/s and protons move to the left at 3485 m/s.3485 m/s. the particles are evenly spaced with 0.0288 m0.0288 m between electrons and 0.0662 m0.0662 m between protons. assuming that there are no collisions and that the interactions between the particles are negligible, what is the magnitude of the average current in this region?
