Electrons in a beam are accelerated from rest through a potential difference ΔV. The beam enters an experimental chamber through a small hole. As shown in Fig. 1.35, the electron velocity vector lie within a narrow cone of half angle ϕ oriented along the beam axis. We wish to use a uniform magnetic field directed parallel to the axis to focus the beam, so that all of the electrons can pass through a small exit port on the opposite side of the chamber after they travel the length d of the chamber. What is the required magnitude of the magnitude field?

Protons having a kinetic energy of 50 MeV are moving in the positive x-direction and enter a magnetic field B = 0.5 mT ( k ) directed out of the plane of the page and extending from x = 0 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 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.
