In an experiment we wish to find how many hydrogen atoms in a gas have their electrons ionized (removed). They are accelerated through a 4.50 MV potential and fired in the positive x-direction towards a magnetic field of magnitude B = 0.045 T. The field points out of the plane, in the positive z direction. The field exists from x = 0 to x = 1.00 m. (a) What shape is the trajectory of the ionized hydrogen atoms? Explain. Hint: is it parabolic (proportional to x^2) as it would be for projectile motion under gravitational forces, is it circular as it would be for an object in uniform circular motion, linear like parachute at terminal velocity, exponential like interest calculations and atomic bombs, something else? (b) Calculate the y component of an ionized hydrogen atom's momentum as they leave the magnetic field. (c) Find the angle 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. (d) Why would the trajectory differ for a non-ionized hydrogen atom? What would be that trajectory
