Question 1302d

Vectors II: Lines and Planes
Perpendicular Distance between Lines

Question

The line l{l} is given by
l1:r=(−2−15)+λ(122),  λ∈R. l_1: \mathbf{r} = \begin{pmatrix} - 2 \\ - 1 \\ 5 \end{pmatrix} + \lambda \begin{pmatrix} 1 \\ 2 \\ 2 \end{pmatrix}, \; \lambda \in \mathbb{R}.
Find the perpendicular distance between the line and the point B(−3,−1,0).{B \left( - 3, - 1, 0 \right).}
