Chapter 29163Q29.17The proton will veer upward when it enters the field and move in a counter-clockwise semicirculararc. An electron would turn downward and move in a clockwise semicircular arc of smaller radiusthan that of the proton, due to its smaller mass.Q29.18Particles of higher speeds will travel in semicircular paths of proportionately larger radius. They willtake just the same time to travel farther with their higher speeds. As shown in Equation 29.15, thetime it takes to follow the path is independent of particle’s speed.Q29.19The spiral tracks are left by charged particles gradually losing kinetic energy. A straight path mightbe left by an uncharged particle that managed to leave a trail of bubbles, or it might be theimperceptibly curving track of a very fast charged particle.Q29.20No. Changing the velocity of a particle requires an accelerating force. The magnetic force is proportional
