(a) Singly charged uranium-238 ions are accelerated through a potential difference of 1.60 kV and enter a uniform magnetic field of 1.40 T directed perpendicular to their velocities. Determine the radius of their circular path.

1 cm

(b) Repeat for uranium-235 ions.

2 cm

(c) How does the ratio of these path radii depend on the accelerating voltage ΔV and on the magnitude of the magnetic field strength B?

3

It is proportional to ΔV / B. It is inversely proportional to ΔV / B. It is proportional to ΔV multiplied by B. It is inversely proportional to ΔV multiplied by B. It is independent of ΔV and B
