At the Equator near Earth’s surface, the magnetic field is approximately 82.2 µT northward and the electric field is about 143 N/C downward in fair weather. A electron travels with an instantaneous velocity of 2.42 × 106 m/s directed to the east in this environment. The acceleration of gravity is 9.8 m/s 2 . Find the magnitude of the gravitational force on the electron. Answer in units of N.
