Protons having a kinetic energy of 5.00 MeV (1 eV = 1.60 x 10-19J) are moving in the positive x direction and enter a magneticfield B = 0.025 T directed out of the plane of the page andextending from x = 0 to x = 1.00 m as shown in the Figure below.(a) Ignoring relativistic effects, find the angleα between the initial velocity vector of the proton beam and thevelocity vector after the beam emerges from the field.(b) Calculate the y component of the protons’momenta as they leave the magnetic field.
