Question
Let \( L_1 \) be the line passing through the point \( P_1(-5, -1, -3) \) with direction vector \(\mathbf{d} = [3, 2, 1]^T\), and let \( L_2 \) be the line passing through the point \( P_2(1, 2, 1) \) with the same direction vector. Find the shortest distance \( d \) between these two lines, and find a point \( Q_1 \) on \( L_1 \) and a point \( Q_2 \) on \( L_2 \) so that \( d(Q_1, Q_2) = d \). Use the square root symbol ‘\(\sqrt{}\)’ where needed to give an exact value for your answer.

\[
d = 0
\]

\[
Q_1 = (0, 0, 0)
\]

\[
Q_2 = (0, 0, 0)
