Calculate the y-component of the protons’ momentum as they leave the magnetic field. b. Find the angle ϕ between the initial velocity vector of the proton beam and the velocity vector after the beam emerges from the field. Ignore relativistic effects and note that 1eV = 1.60 × 10^−19 J and mass of proton mp = 1.6 x 10^-27 kg.
