Use the following information to answer the next question. Magnetic Field Mass Spectrometer Eleetrica 3.1 x 10-3 T agnetic field directed out of the page Path of protons In a magnetic field mass spectrometer, protons are accelerated from rest through a potential difference and then enter a magnetic field of strength 3.1 x 10 T. The magnetic field deflects the protons in a circular path as shown above. The measured radius of the protons is 1.3 m 1. Determine the potential difference used to accelerate the protons.
