b. r = 1.2 x 10-2m c.r = 1.2 x 10-³m d. r = 1.2 x 104m
6. A proton having a speed of 5.0 x 106 m/s in a magnetic field feels a force of 8.0 x 10 -14 N
toward the west when it moves vertically upward. When a horizontally in a northerly
direction, it feels zero force. What is the magnitude of magnetic field in this region?
a. 0.05 T
b. 0.07T
