An ion with charge 1.6 ×× 10−19−19 CC moves at speed 1.0 ×× 1066 m/sm/s into and perpendicular to the 0.30-TT magnetic field of a mass spectrometer. After entering the field, the ion moves in a circular path of radius 0.36 mm. What physical quantities describing the field and the ion can you determine using this information? Check all that apply. the magnitude of the magnetic force on the ionthe mass of the ionthe direction of the magnetic fieldthe potential difference in the velocity selector
