Inside a mass spectrometer an atom is ionized so that it has a charge of q = +1.6x10-19 C and is then accelerated to a speed of 5.0 x 10 m/s. The atom then enters a region of uniform magnetic field with a strength of 0.5 T. This field deflects the atom into a circular trajectory as shown. The atom completes an exact semicircle before hitting the detector a distance of d = 2.5 cm away from where it entered the magnetic field. Based upon this information, what is the mass of the atom?
