Question

An electron moves horizontally across the Earth's equator at a speed of 2.50 106 m/s and in a direction 35.0° N of E. At this point, the Earth's magnetic field has a direction due north, is parallel to the surface, and has a value of 3.00 10-5 T. What is the force acting on the electron due to its interaction with the Earth's magnetic field?
a.6.88 10-18 N due west
b.6.88 10-18 N toward the Earth's surface
c.9.83 10-18 N toward the Earth's surface
d.9.83 10-18 N away from the Earth's surface
e.4.00 10-18 N away from the Earth's surface
