University of Virginia Velocity Selector in a Mass Spectrometer Questions

 

A mass spectrometer accepts ions from the velocity selector and it is configured as below.. An ion (1+) enters the mass spectrometer at the point indicated.

– Draw the direction of the force as the ion enters the magnetic field.

– Draw the path the particle will take to the detector.

– Derive an expression for the mass in terms of all other relevant parameters for this instrument.

– An impact is detected at 2 cm away from the injection port. If the magnitude of the magnetic field is 0.1 T and particle speed is 1000 m/s, what is the mass of the 1+ ion?
