Task id17045

In the Bainbridge mass spectrometer (Fig. 28.13), the distance between the exit from the velocity filter (selector) and the entrance slit of the recording device is fixed and equal to l = 400 mm. The magnetic field induction in both parts of the device is the same and equal to 5.00·10-2 T. With a smooth change in the electric field in the velocity filter, peaks of the anode current in the receiver are observed at voltages of 1.20 x 104 V/m and 1.6 x 104 V/m. Assuming the ions are singly charged, identify them (i.e. determine which chemical element they correspond to).
