A 2.0 cm segment of a wire, centered at the origin (0, 0, 0) lies along X-axis. It carries a current of 4.0 A in positive X-direction. The magnetic field due to this segment at a point (0, 4.0 m, 0) is [($\frac{{\mathit{\mu }}_0}{4\mathit{\pi }}$) = 10^-7 Tm/A, and i, j and k are unit vectors along X-axis, Y-axis and Z-axis, respectively]:
