In the Bainbridge mass spectrometer (see Figure 27.24 in the textbook), the magnetic-field magnitude in the velocity selector is 0.650 T, and ions having a speed of 1.82×10^6m/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 plates P and P'?
