In an experiment, we wish to find how many hydrogen atoms in a gas have their electrons ionized (removed). They are accelerated through a 4.5 MV potential and fired in the positive x-direction towards a magnetic field of 0.045 T magnitude. The magnetic field points out of the screen toward you in the positive z-direction. The magnetic field region starts from x = 0 and ends at x = 1 m.

1. Calculate the y-component of an ionized hydrogen atom’s momentum as they leave the magnetic field.

2. Find the angle (alpha) between the initial velocity vector of the ionized hydrogen’s atoms beam and the final velocity vector after the beam emerges from the field. (Ignore relativistic effects if you know what I’m talking about.)

3. Why would the trajectory differ for a non-ionized hydrogen atom? What would be that trajectory?
