4) [8 pts] A simple mass spectrometer works by sending particles of known charge and velocity into a
region of uniform magnetic field and measuring their impact on a flat detector. If two particles with the
same charges (+q) both enter a mass spectrometer of known magnetic field strength (B into the page)
and at the same velocity (v), then what is the mass of the heavier particle, m?, in terms of the lighter
particle, m, if they strike the detector as shown a distance d apart?
