Vectors $\vec a = \hat i - 2\hat j + 3\hat k$ and $\vec b = 3\hat i - 6\hat j + 9\hat k$ are:

  1. Perpendicular
  2. Equal
  3. Linearly independent (non-collinear)
  4. Linearly dependent (collinear)
Show answer and solution

Correct answer: D. Linearly dependent (collinear)

$\vec b = 3\vec a$, so $\vec b$ is a scalar multiple of $\vec a$. They are linearly dependent, i.e. collinear.
