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 8339 V/m, and the magnetic fields in both the velocity selector and the deflection chamber have magnitudes of 0.0936 T. In the deflection chamber the particle strikes a photographic plate 55.5 cm removed from its exit point after traveling in a semicircle.



(a) What is the mass-to-charge ratio of the particle?

2.915e-07 kg/C



(b) What is the mass of the particle if it is doubly ionized?

9.328e-26 kg



(c) What is its identity, assuming it's an element?

??????
