Two species of singly charged positive ions of masses 20.0 x 10–27 kg and 23.4 x 10–27 kg enter a magnetic field at the same location with a speed of 1.00 x 105 m/s. If the strength of the field is 0.200 T, and the ions move perpendicularly to the field, find their distance of separation after they complete one-half of their circular path.
