Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

$|\mathbf v |=$ Unnamed gap

(Give your answer to 2 decimal places where necessary)

Advice

For a vector of the form $\mathbf a = \begin{pmatrix} a_1 \\ a_2 \\ a_3 \end{pmatrix}$ , the magnitude is found by calculating the square root of the sum of the components squared:

$|\mathbf a| = \sqrt{a_1^2+a_2^2+a_3^2}.$

Therefore, for the vector $\mathbf v = \var{v}$ ,

{advice}
