Chapter 29 163 Q29.17 The proton will veer upward when it enters the field and move in a counter-clockwise semicircular arc. An electron would turn downward and move in a clockwise semicircular arc of smaller radius than that of the proton, due to its smaller mass. Q29.18 Particles of higher speeds will travel in semicircular paths of proportionately larger radius. They will take just the same time to travel farther with their higher speeds. As shown in Equation 29.15, the time it takes to follow the path is independent of particle’s speed. Q29.19 The spiral tracks are left by charged particles gradually losing kinetic energy. A straight path might be left by an uncharged particle that managed to leave a trail of bubbles, or it might be the imperceptibly curving track of a very fast charged particle. Q29.20 No. Changing the velocity of a particle requires an accelerating force. The magnetic force is proportional
