A beam of particles (each particle has a charge q = -2e and a kinetic energy of 4.00 × 10-13 the magnetic field of a bending magnet as shown in Figure 19-32. The radius of curvature of the beam j) is deflected by is 20.0 cm, and the strength of the magnetic field is 1.50 T. (a) What is the mass of the par- ticles making up the beam? (b) Sketch the path for the given ions in the given magnetic field as a reference path. Then sketch a path for a more massive doubly ionized negative ion and a less massive doubly ionized positive ion, both with the same speed as the given ions, for comparison. Answer: (a) 1.15 x 10-26 kg 20 cm A beam of particles (each particle has a charge q = -2e and a kinetic energy of 4.00 × 10-13 the magnetic field of a bending magnet as shown in Figure 19-32.
