Protons having a kinetic energy of 5.00 MeV are moving in the positive x direction and enter a magnetic field B = 0.050 0kˆ T directed out of the plane of the page and extending from x = 0 to x = 1.00 m, as shown in Figure P29.55.
(a) Calculate the y component of the protons€™ momentum as they leave the magnetic field.
(b) Find the angle 1 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 1 eV = 1.60 x 10-19 J.
