A beam of protons traveling at 1.60 km/s enters a uniform magnetic field, traveling perpendicular to the field. The beam exits the magnetic field, leaving the field in a direction perpendicular to its original direction (the figure (Figure 1) ). The beam travels a distance of 1.20 cm while in the field.
Why is the angle π/2?
