A particle travels under the influence of electric and magnetic fields. In its point of view, the magnetic field points downward and the electric field points from left to right (both fields are perpendicular to the motion of the particle). If the direction of the particle did not change as it passes through this region, then a.) its velocity is the ratio of the magnitudes of the electric and magnetic fields, assuming it is positively charged. b.) its velocity is the ratio of the magnitudes of the electric and magnetic fields, assuming it is negatively charged. c.) the particle is uncharged.
