An electric field perpendicular to a magnetic field is used as a velocity selector for Li+ ions, selecting the velocity v1. Next, Li++ ions are sent through the same velocity selector, selecting velocity v2. If neither the electric nor magnetic fields have changed between the two processes, how do v1 and v2 compare?
