A charge of 26 coulombs (not micro-coulombs) with a mass of 8 kg is traveling in a helix in a uniform magnetic field directed in the +z direction. The helix has a radius of 12.2 meters. In a time of 0.17 seconds, the charge's displacement in the +z direction is 2.2 meters. If the magnitude of its (total) velocity is 58 m/s, what is the amount of the magnetic field in Tesla?
