Two long wires carrying current $I_{1} and I_{2}$ are arranged as shown in the figure. The one carrying current $I_{1}$ is along the x-axis. The other carrying current $I_{2}$ is along a line parallel to the y-axis given by x = 0 and z = d. Find the force exerted at $O_{2}$ because of the wire along the x-axis.
