(F. F. Chen ~2.7) An electron beam with density \(n_e=10^{14}\) m\(^{-3}\) and radius \(R=1\) cm crosses a region with a uniform magnetic field \(\vec{B}=B_0\vec{u}_z\), where \(B_0=2\) T and the \(zz\) axis is aligned with the direction of propagation of the beam. Determine the direction and magnitude of the \(\vec{E}\times\vec{B}\) drift at \(r=R\) (note that \(\vec{E}\) is the electrostatic field created by the charge of the beam).
