In the New England, the horizontal component of the earth's magnetic field has a magnitude of 1.61E-5 T. An electron is turn vertically straight up from the ground with a speed of 2.11E+6 m/s. Define what is the magnitude of the acceleration caused by the magnetic force? Overlook the gravitational force acting on the electron.
