At the equator, near the surface of the Earth, the magnetic field is approximately 50.0 μT northward, and the electric field is about 90.0 N/C downward in fair weather. Find the gravitational, electric, and magnetic forces on an electron in this environment, assuming that the electron has an instantaneous velocity of 8.00 ✕ 106 m/s directed to the east.

gravitational force = m*g

= 9.1*10^-31 * 9.8

= 8.92*10^-30 N

acts downward

electric force = q*E

= (1.6*10^-19)*(90)

= 1.44*10^-17 N

DIRECTION : upward

magnetic force = q*V*B

= (1.6*10^-19)*(8*10^6)*(50*10^-6)

= 6.4*10^-17 N

direction = downward
