Magnetic Force direction on a charged particle moving parallel to a wire

Homework Statement

Homework Equations

The right hand curl rule gave me the counterclockwise direction for the magnetic field but I am confused about how is it going to work for the particle. Thanks

By using the right hand rule for the magnetic field from the wire, you need to determine which direction that the magnetic field ## \vec{B} ## points at the position of the particle. You then need to compute the direction of the force ## \vec{F}=Q( \vec{v} \times \vec{B} ) ## using the right hand rule for the vector cross product.

Thanks for your answer. I tried doing that and I am not able to get the direction at the point at which the particle is. Lastly, which right hand rule do we use to find the force? (Fleming's or the other right hand rule)

For a wire, I always remember the ## B ## field direction as being clockwise (pointing down on the right side) when the current is into the paper=I really don't use a right hand rule for it. You need to translate that when the wire is running along the paper.
