Two long wires carrying current I1 and I...

Two long wires carrying current `I_1` and `I_2` are arranged as shown in Fig. EP 4.16. 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.
