Two long parallel conductors $\mathrm{S}_1$ and $\mathrm{S}_2$ are separated by a distance 10 cm and carrying currents of 4A and 2A respectively. The conductors are placed along x-axis in X-Y plane. There is a point P located between the conductors (as shown in figure). A charge particle of $3 \pi$ coulomb is passing through the point P with velocity $\vec{v}=(2 \hat{i}+3 \hat{j}) \mathrm{m} / \mathrm{s}$; where $\hat{i} \& \hat{j}$ represents unit vector along x & y axis respectively. The force acting on the charge particle is $4 \pi \times 10^{-5}(-x \hat{i}+2 \hat{j}) \mathrm{N}$ . The value of x is : A
