A particle in the cyclotron shown in Figure 28.16a gains energy qAV from the alternating power supply each time it passes from one dee to the other. The time interval for each full orbit is T = 21 = 2am qB so the particle's average rate of increase in energy is 29AV – g°BAV T. Notice that this power input is constant in time. On the other hand, the rate of increase in the radius r of its path is not constant. (a) Show that the rate of increase in the radius r of the dr 1 Δν particle's path is given by dt r nB

Question
A particle in the cyclotron shown in Figure 28.16a gains energy qAV from the alternating
power supply each time it passes from one dee to the other. The time interval for each full
2qAV
g*BAV
2nm
orbit is T = 21
so the particle's average rate of increase in energy is
qB
Notice that this power input is constant in time. On the other hand, the rate of increase in the
radius r of its path is not constant. (a) Show that the rate of increase in the radius r of the
dr
1 Δν
particle's path is given by
dt
r nB
