An electron moving along x axis is deflected along the -y axis as it enters a magnetic field. From the deflection I infer that the direction of the magnetic field points Enter 1 for A), 2 for B), 3 for C), 4 for D), 5 for E) A) along z axis. B) along -z axis. C) along -x axis. D) along x axis. E) along -y axis.
