The shortest distance between lines $\mathrm{L}_1$ and $\mathrm{L}_2$, where $\mathrm{L}_1: \frac{\mathrm{x}-1}{2}=\frac{\mathrm{y}+1}{-3}=\frac{z+4}{2}$ and $\mathrm{L}_2$ is the line passing through the points $A(-4,4,3) \cdot B(-1,6,3)$ and perpendicular to the line $\frac{x-3}{-2}=\frac{y}{3}=\frac{z-1}{1}$, isV
