An ion, stripped of a single electron, enters the magnetic field B of a mass spectrometer with a velocity v as shown.  It hits the detector a distance 2r from place where it enters the B-field.  The direction of the B-field is into the page.  Which is/are all the change(s) that INCREASE the distance travelled by the ion from the place where it enters the B-field to where it hits the detector?
