Protons having a kinetic energy of 5 MeV...

Protons having a kinetic energy of 5 MeV are moving in the positive x-direction and enter a magnetic field `B=0.0500 hat k T` directed out of the plane of the page and extending from `x=0 to x=1 m` as shown in Fig. 1.34.
a. Calculate the y-component of the protons' momentum as they leave the magnetic field.
b. Find the angle `phi` 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 xx 10^(-19) J.`
