2. A mass spectrometer is used to determine the mass of theions in a sample. Once the mass of the ions are known onecan determine what molecular composition of the sample.The Behrend chemistry department has several massspectrometers.A new singly charged ion (the sign of the charge is unknownbut we know it is either +eor-e) enters a velocity selectoras shown with crossed electric and magnetic fields ofmagnitude E and 8. Only ions with the selected speed thenleave through the right hole and enter a region with thesame magnetic field 8 but no electric field. The magneticforce then causes the charges to move in a semi-circularpath of radius as shown. By measuring one candetermine the mass of the ions.a. Is the ion positive or negative?Bdetector-foBb. Determine the mass of the ion in terms of e, 8, E and/or7. Show work. Note: your answer should notcontain the speed v.

A particle passes through a mass spectrometer as illustrated in the figure below. The electric field between the plates of the velocity selector has a magnitude of 8060 V/m, and the magnetic fields in both the velocity selector and the deflection chamber have magnitudes of 0.0920 T. In the deflection chamber the particle strikes a photographic plate 39.6 cm removed from its exit point after traveling in a semicircle. The diagram depicts a velocity selector. The plane of the page is filled with symmetrically arranged crosses labeled vector B0, in above a horizontal plate, and vector Bin below the horizontal plate. Below the horizontal plate, two vertical plates are placed parallel to each other in the right position of the field. The left plate is positively charged and the right plate is negatively charged. The electric field vector E points from the positive plate to the right toward the negative plate. A positively charged particle of charge q and velocity vector v pointing upward…
