A singly charged positive ion has a mass of 2.54 ✕ 10−26 kg. After being accelerated through a potential difference of 254 V, the ion enters a magnetic field of 0.590 T, in a direction perpendicular to the field. Calculate the radius of the path of the ion in the field. A singly charged positive ion has a mass of 2.54 ✕ 10−26 kg.
