An electron in a TV camera tube is moving at 6.20 × 106 m/s in a magnetic field of strength 73 mT. Without knowing the direction of the field, what can you say about the greatest and least magnitude of the force acting on the electron due to the field? (a) Maximum force? (b) Minimum force? (c) At one point the acceleration of the electron is 4.445 × 1016 m/s2. What is the angle between the electron velocity and the magnetic field? (deg)
