A beam of charged particles consisting of protons, electrons, deuterons, and singly ionized helium atoms and H₂ molecules all pass through a velocity selector, all emerging with speeds of 2.5 x 10⁶ m/s. The beam then enters a region of uniform magnetic field B = 0.40 T directed perpendicular to their velocity. Compute the radius of curvature of the path of each type of particle.
