Problem

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}
