Review. A particle with a mass of 2.00 1016 kg and a charge of 30.0 nC starts from rest, is accelerated through a potential difference V, and is fired from a small source in a region containing a uniform, constant magnetic field of magnitude 0.600 T. The particle's velocity is perpendicular to the magnetic field lines. The circular orbit of the panicle as it returns to the location of the source encloses a magnetic flux of 15.0 Wb.
