Think this question might be too ambitious for /sci/.
Not sure how to go about with EM & relativity, I know shit goes a bit crazy.

If this is the addendum:
>>11939429
Then assumption is that relativity clearly doesn't have an effect. With v=c, any particle with mass (like proton) would have infinite kinetic energy.

So going with fully classical assumptions then, using your kinetic energy and field strength, you should be able to get something out.
You'd then have to construct the function of what gets affected and how over time.
Particle will rotate around the axis like pic related, to keep perpendicular to the field. Except, as it starts heading towards the axis, it will just shoot out at some point.
There will be only 2d movement.
Get magnitude of force on particle by magnetic field out, which will always be perpendicular to particle's movement and field's orientation, get your acceleration from there. Use this acceleration to get the radius of the circular path proton makes, and what you can do there is just draw two circles, your 50cm cylindrical region and the new circular path that the particle makes and call it done, or get your angle from there from radiuses of two circles (2 sides same size x2) and one angle at 90deg.
Is that good enough for a start?
Also, what is this entrance exam for?
