A current of 1A1\,\text{A} is flowing along positive xx-axis through a straight wire of length 0.5m0.5\,\text{m} placed in a region of a magnetic field given by B=(2i^+4j^)T\vec{B} = (2\hat{i} + 4\hat{j})\,\text{T}. The magnitude and the direction of the force experienced by the wire respectively are
