The electrons in the beam of a television tube have a kinetic energy of 2.93 x 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 2.66 x 10- T. What is the acceleration of an electron due to this field component? Number UnitsDue to friction with the air, an airplane has acquired a net charge of 1.70 x 10'5 C. The plane moves with a speed of 375 m/s at an angle 6with respect to the earth's magnetic eld, the magnitude of which is 4.21 x 10'5 T. The magnetic force on the airplane has a magnitude of 2.65 x 10'7 N. Find the angle 6. (There are two possible angles. Place the smaller answer as part (3).) 4b (a) Number n Units 4) (b) Number n Units
