Help with question related to magnetism

[Antithesis]

Hello,

I was hoping if any of you could help me with this problem. It's one of the many I have for my homework assignment.

A long straight wire carries a current i. A particle having a positive charge q and mass m kept at a distance x from the wire is projected towards it with a speed u. Find the minimum separation between the wire and the particle.

Any help would be greatly appreciated. I'm in high school, btw.

Thank you.
