Question
(Figure 1) shows a mass spectrometer, an analytical
instrument used to identify the various molecules in a
sample by measuring their charge-to-mass ratio q/m.
The sample is ionized, the positive ions are accelerated
(starting from rest) through a potential difference AV,
and they then enter a region of uniform magnetic field.
The field bends the ions into circular trajectories, but after
just half a circle they either strike the wall or pass through
a small opening to a detector. As the accelerating voltage
is slowly increased, different ions reach the detector and
are measured. Consider a mass spectrometer with a
200.00 mT magnetic field and an 8.0000 cm spacing
between the entrance and exit holes.
