The distance between the lines $\vec{r}=\hat{i}-2 \hat{j}+3 \hat{k}+\lambda(2 \hat{i}+3 \hat{j}+6 \hat{k})$ and $\vec{r}=3 \hat{i}-2 \hat{j}+1 \hat{k}+\mu(4 \hat{i}+6 \hat{j}+12 \hat{k})$ is: |
$\frac{\sqrt{28}}{7}$ $\frac{\sqrt{199}}{7}$ $\frac{\sqrt{328}}{7}$ $\frac{\sqrt{421}}{7}$ |
$\frac{\sqrt{328}}{7}$ |
The correct answer is Option (3) → $\frac{\sqrt{328}}{7}$ |
