Problem 27.8: Mass spectrometer
Please wait for the animation to completely load.
The animation shows a particle passing through a mass spectrometer (position is given in meters and time is given in seconds). There is a constant magnetic field throughout the region directed into the screen. There is a constant electric field in the first region only. Restart.
- Is the particle charged? How do you know? If it is charged, does it have a positive or negative charge? Justify your answer.
- If the electric field produced by the charged plates in the first region is 80 N/C, what is the value of the magnetic field in that region?
- What is the charge-to-mass ratio (q/m) of the particle?
For an introduction to the mass spectrometer see Exploration 27.3.
