Find the magnitude of the magnetic force (FB) of an electron moves through space with a speed of v= 8.0x106m/s along the x axis. At its location, the magnetic field of the Earth has a magnitude of B= 5 X10-5 T, and is directed at an angle of 90o to the x axis. (Hint: q= -1.6X10-6) 64 X10-5 N 0 8 X10-5 N 70 X10-5 N
