In an experiment with cosmic rays, a vertical beam of particles that have charge of magnitude 3e and mass 12 times the proton mass enters a uniform horizontal Part A magnetic field of 0.250 T and is bent in a semicircle of diameter 95.0 cm, as shown in (Figure 1). Find the speed of the particles. Express your answer in meters per second. ? Figure < 1 of 1 m/s
