At the Equator near Earth's surface, the magnetic ?eld is approximately 64.5 µT northward and the electric ?eld is about 51 N/C downward in fair weather. A electron travels with an instantaneous velocity of 1.13 × 10^6 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, find the magnitude of the electric force on the electron, and find the magnitude of the magnetic force on the electron.
