Question
A certain commercial mass spectrometer is used to separate uranium ions of mass 3.92 × 10-25 kg and charge 3.20 × 10-¹⁹ C from
related species. The ions are accelerated through a potential difference of 122 kV and then pass into a uniform magnetic field, where
they are bent in a path of radius 1.03 m. After traveling through 180° and passing through a slit of width 0.923 mm and height 1.19 cm,
they are collected in a cup. (a) What is the magnitude of the (perpendicular) magnetic field in the separator? If the machine is used to
separate out 1.17 mg of material per hour, calculate (b) the current of the desired ions in the machine and (c) the thermal energy
produced in the cup in 1.15 h.
