Question
![**Experiment with Cosmic Rays**
In an experiment with cosmic rays, a vertical beam of particles with a charge of magnitude 3e and a mass 12 times that of a proton enters a uniform horizontal magnetic field of 0.250 T. The beam is bent into a semicircle with a diameter of 95.0 cm, as shown in Figure 1.
**Figure Explanation**
The diagram shows a semicircular path with a diameter of 95.0 cm, represented by a dashed line. The path is in a plane perpendicular to a magnetic field \(\mathbf{B}\), which is directed horizontally, as indicated by the blue dots (representing the field's direction coming out of the page).
