Two long parallel conductors S 1 and S 2 are separated by a distance 10 cm and carrying currents of 4 A and 2 A 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 π coulomb is passing through the point P with velocity ) j ˆ 3 i ˆ 2 ( v + = G m/s; where i ˆ and j ˆ represents unit vector along x & y axis respectively. The force acting on the charge particle is 4 π ×10 − 5 ( j ˆ 2 i ˆ x + − )N. The value of x is:
