A 1 cm segment of a wire lying along x-axis carries current of 0.5 A along +x direction. A magnetic field $\vec{B} = (0.4 \text{ mT}) \hat{j} + (0.6 \text{ mT}) \hat{k}$ is switched on, in the region. The force acting on the segment is (A) $$2\hat{j} + 3\hat{k}$ \text{ mN}$ (B) $$-3\hat{j} + 2\hat{k}$ \mu\text{N}$ (C) $$6\hat{j} + 4\hat{k}$ \text{ mN}$ (D) $$-4\hat{j} + 6\hat{k}$ \mu\text{N}$
