Doubly-ionized particles with an atomic mass of 59.4 u are moving due N at a speed of 7.78 x 105 m/s when they enter a uniform magnetic field of strength, B = 35.5 mT. The ions, which are moving perpendicular to the field, follow a circular path of radius, r, and travel north a distance, h = 2.02 m, before leaving the field at an angle, 8, as shown in the figure. (a) What is the radius of the ions' circular path? r = 6.793✔ m (b) At what angle do the ions leave the field? 0 = 73.44 X h 2
