A proton moves with an unknown velocity through a magnetic field of 6.79 x 10-4 T that points directly south. The proton experiences a force of 3.45 x 10-16 N directly east. What is the magnitude of the velocity? (charge of a proton is +1.6x 10-19 C) 1.23 x 106 m/s 3.18 x 107 m/s 1.23 x 107 m/s 3.18 x 106 m/s
