In an experiment electrons are first sent through a velocity selector region and then into a magnetic field only region. Electrons exit the velocity selector moving horizontally to the right and are collected on a plate a distance d below the velocity selector exit as shown. On the diagram, indicate the direction of the required magnetic field and electric field. Assume the magnetic field is the same direction in both regions. Region I, E and B₁ velocity selector Screen e's hit Region II, B2 only d I I I I I I I
