Question
27.32 In the Bainbridge mass spectrometer (see Fig. 27.24), the magnetic-field magnitude in the velocity selector is 0.510 T, and ions having a speed of 1.82 x 106 m/s pass through undeflected.
(a) What is the electric-field magnitude in the velocity selector?
(b) If the separation of the plates is 5.20 mm, what is the potential difference between the plates?
