Protons having a kinetic energy of 4.70 MeV are moving in the positive x-direction and enter a magnetic field of 0.0670 T in the z-direction, out of the plane of the page, and extending from x = 0 to x = 1.00 m as in the figure below. x= 1.00 m (a) Calculate the y-component of the protons' momentum as they leave the magnetic field. (Indicate the direction with the sign of your answer.) |kg · m/s (b) Find the angle a between the initial velocity vector of the proton beam and the velocity vector after the beam emerges from the field. Hint: Neglect relativistic effects and note that 1 eV = 1.60 x 10°19 J.
