and has a magnitude of 2.25 × 10^−5 T (a) In what direction are the electrons deflected by this field component? (b) What is the acceleration of an electron in part (a)? The electrons in the beam of a television tube have a kinetic energy of 4.5 ×10^−15 J Initially the electrons move horizontally from west to east. The vertical component of the earth's magnetic field points down toward the surface of the earth
