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 58.0 cm removed from its exit point after traveling in a semicircle.

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 58.0 cm
removed from its exit point after traveling in a semicircle.
