An ion with a charge of +1.60 x 10-19(1 is accelerated in a powerful electric field. The mass of the ion is unknown. The ion starts at rest at the positive plate, and accelerates through a voltage difference of 5.00 x 103 V. The ion enters a magnetic field of strength 0.315 T immediately after it leaves the electric eld that caused the acceleration. At this point, it is traveling perpendicular to the magnetic field. In the field, the ion curves through a circle of radius = 5.0 cm, then strikes a detector.
