MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question 1) Alpha particles (charge = + 2 e , mass = 6.68 × 10 - 27 kg) are accelerated in a cyclotron to a final orbit radius of 0.60 m. The magnetic field in the cyclotron is 0.10 T. The period of circular motion of the alpha particles is closest to: A) 1.3 μs B) 2.0 μs C) 2.6 μs D) 3.2 μs E) 3.9 μs 1) 2) If you were to cut a small permanent bar magnet in half, A) one piece would be a magnetic north pole and the other piece would be a south pole. B) neither piece would be magnetic. C) each piece would in itself be a smaller bar magnet with both north and south poles. D) each piece would contain both north and south poles, but on a given piece the intensity of the north and south poles would not necessarily be equal. E) None of these statements is true. 2) Figure 27.1 3) In Fig. 27.1 is a velocity selector that can be used to measure the speed of a charged particle. A beam of particles is directed along the axis of the instrument. A parallel plate capacitor sets up an
