Alpha particles (charge = +2e,mass = 6.68 × 10^-²⁷ kg,e = 1.60 × 10^-19C)0.87 μs. A) 0.44 μs. B) 0.67 μs. C) are accelerated in a cyclotron to a final orbit radius of 0.90 m. The magnetic field in the cyclotron is 0.30 T. The period of the circular motion of the alpha particles is closest to D) 1.1 μs.

Question

Quizplus · Accepted Answer

The period of circular motion in a cyclotron is given by T = (2πm)/(qB). Substituting the given values, T = (2π * 6.68 × 10^-27 kg) / (2 * 1.60 × 10^-19 C * 0.30 T) ≈ 0.44 μs.
