An ion having charge +6e is traveling horizontally to the left at 8.60km/s when it enters a magnetic field that is perpendicular to its velocity and deflects it downward with an initial magnetic force of 7.04×10^-15N. What is the direction of this field?
1. The field is directed out of the screen.
2. The field is directed into the screen.
3.The field is directed to the right.
4. The field is directed tot he left. What is the magnitude of this field?
