[\mathbf{B}(\mathbf{r}) = \frac{\mu_0}{4\pi} \int_C \frac{I d\mathbf l\times\mathbf{r}}{|\mathbf{r}|^3}]

Magnetic field by a given segment of wire.

In this case we have the length of the segment of the wire to be 2mm and also the distance to the desired point is given alongwith th angle it makes with the the segment.

\Theta =\pi /4
put the values of current and other constants in the expression to get the final answer.
