Question

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) Calculate the y component of an ionized hydrogen atom’s momentum as they leave the magnetic field. (b) Find the angle α 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. (c) Why would the trajectory differ for a non-ionized hydrogen atom? What would be that trajectory?

Answer 1

​*It may be noted that since magnetic field doesn't do any work, KE,speed and magnitude of momentum, all remain unchanged.
