Short Answer
An ion enters a mass spectrometer which has a 0.18 Tesla field perpendicular to
an electric field of 1.6 kV/m and selects a velocity. The same magnetic field is then
used to deflect the singly charged ion into a circular path of radius 12.5 cm.
(a) What velocity was selected?
(b) What was the ion mass?
