Atomic Mass Unit

When the particle enters the magnetic field, the magnetic force provides the centripetal force to cause the particle to execute uniform circular motion: Since v and B are the same for all the particles, the largest r is found by maximizing the ratio m/|q|. Furthermore, since the ratio of u/e (atomic mass unit/magnitude of electric charge) is a constant, the answer depends only on the ratio of “factor of u” to “factor of charge.” The ratio 20/1 is largest, so it will have the largest r.
