magnetic field due to current carrying wire

A long straight wire AB carries a current of 4 A. A proton P travels at 4xx10^(6) ms^(-1) parallel to the wire 0.2 m from it and in a direction opposite to the current as shown in the figure. Calculate the force which the magnetic field due to the current carrying wire exerts on the proton. Also specify its direction.
