An oxygen-16 ion with a mass of 2.66 ✕ 10−26 kg travels at 3.00 ✕ 106 m/s perpendicular to a 1.90 T magnetic field, which makes it move in a circular arc with a 0.03281 m radius. What positive charge (in C) is on the ion? C (b) What is the ratio of this charge (q) to the charge of an electron (qe)? q qe = (c) Discuss why the ratio found in (b) should be an integer.
