(F. F. Chen ~2.7) An electron beam with density ne=1014 m−3 and radius R=1 cm crosses a region with a uniform magnetic field →B=B0→uz, where B0=2 T and the zz axis is aligned with the direction of propagation of the beam. Determine the direction and magnitude of the →E×→B drift at r=R (note that →E is the electrostatic field created by the charge of the beam).
