(a) an oxygen‐16 ion with a mass of 2.66 10 kg 26 travels at 5.00 10 m/s 6 perpendicular to a 1.20‐t magnetic field, which makes it move in a circular arc with a 0.231‐m radius. what positive charge is on the ion?
(b) what is the ratio of this charge to the charge of an electron?
(c) discuss why the ratio found in (b) should be an integer.
