Magnetic Effects of Current and Magnetism: JEE Main 2025 Physics question

Two long parallel wires X and Y, separated by a distance of 6 cm, carry currents of 5A and 4A, respectively, in opposite directions as shown in the figure. Magnitude of the resultant magnetic field at point P at a distance of 4 cm from wire Y is $x \times 10^{-5}$ T. The value of x is ______. Take permeability of free space as $\mu_0 = 4\pi \times 10^{-7}$ SI units.
