(a) What is the total current?(b) What are the direction and magnitude of the electric force acting on an individual electron within the beam as a function of its radius r from the beam central axis? Consider only an electron within the beam i.e. r (c) What are the direction and magnitude of the magnetic force acting on that electron (which is moving at v) vs. radius from the beam axis again just for r (d) If v3x10^6 m/s i.e. roughly 1% of the speed of light what is the numerical value of the ratio of the magnitudes of the magnetic to electric forces?
