Amass spectrometer is to be used to separate protons from deuterium nuclei. a deuterium nucleus has the same charge and twice the mass as a proton, since it contains an extra neutron. both the deuterium and the proton nuclei are accelerated by the same voltage. which of the following statements is true?

answers:
the deuterium will not be deflected in the mass spectrometer, since it contains a neutron.
both the proton and the deuterium will move along the same circular path.
the deuterium will have a larger radius of curvature, since it is more massive.
mass spectrometers cannot be used to analyze nuclei, only molecular ions.
the deuterium will have a smaller radius of curvature, since it is more massive.
