in new england, the horizontal component of the earth's magnetic field has a magnitude og 1.6x10^-5 T. An electron is shot vertically striaght up from the ground with a speed of 2.1x10^6 m/s. what is the magnitude of acceleration caused by the magnetic force? Ingore the gravitational force on the electron.
a = F/m = qvB/m = (1.6E-19)*(2.1E6)*(1.6E-5)/(9E-31) = 5.9733E12 m/s²
