A proton, traveling with a velocity of 2.5 × 106 m/s due east, experiences a magnetic force that has a maximum magnitude of 5.1 × 10-14 N and direction of due south. What are the magnitude and direction of the magnetic field causing the force? If the field is up, then enter a number greater than zero. If the field is down, then enter a number less than zero.
