Magnetic Effects of Current and Magnetism: JEE Main 2023 Physics question

Two long parallel wires carrying currents 8A and 15A in opposite directions are placed at a distance of 7 cm from each other. A point P is at equidistant from both the wires such that the lines joining the point P to the wires are perpendicular to each other. The magnitude of magnetic field at P is _____________ $\times~10^{-6}$ T. (Given : $\sqrt2=1.4$)
