The electrons in the beam of a television tube have a kinetic energy of 2.40 × 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, and has a magnitude of 1.67 × 10-5 T. What is the acceleration of an electron due to this field component?
