What is the magnitude and direction of the magnetic force on the electron?
An electron travels 8.03 x 10^5 m/s horizontally to the east. A 0.68 T magnetic field acts perpendicular to its motion. What is the magnitude and direction of the magnetic force on the electron?
7.45 x 10-14 N to the north
7.45 x 10-14 N to the west
8.74 x 10-14 N to the east
8.74 x 10-14 N to the north
9.11 x 10-14 N to the east
