A thin wire of length 1 m is placed perpendicular to the XY plane. If it is moved with velocity $\vec{v}=4 \hat{\imath}-\hat{\jmath} \mathrm{m} / \mathrm{s}$ in the region of magnetic induction $\vec{B}=\hat{\imath}+4 \hat{\jmath} \mathrm{~Wb} / \mathrm{m}^2$. The potential difference developed between the ends of the wire is
