Asingly-charged ion enters a velocity selector that has a 0.18-t magnetic field perpendicular to an electric field of 1.6 kv/m, with both fields perpendicular to the velocity of the ion. the same magnetic field is then used to deflect the ion into a circular path of radius 12.5 cm. what velocity was selected by the velocity selector?
