Ions with a charge of 1 e travel at a speed v = 4.7 * 10⁶ m/s at right angles to a field of 3.6 T.If the ions travel in a circle of radius R = 0.47 m,what is their mass?

Question

Quizplus · Accepted Answer

The centripetal force required for circular motion is provided by the magnetic force: qvB = mv²/R. Solving for m gives m = qBR/v. Substituting q = 1.6 * 10^-19 C, B = 3.6 T, R = 0.47 m, and v = 4.7 * 10^6 m/s, we find m = 0.576 * 10^-25 kg.
