Question

Find the $\parallel v\parallel$, if$v=6i+2j$

Short answer

The solution is$\parallel v\parallel =6.324$, if$v=6i+2j$

Step-by-step solution

step 1.Given information

$v=6i+2j$

step 2.solution

We already know that $\parallel v\parallel =\sqrt{{\left(a\right)}^2+{\left(b\right)}^2}$if $v=ai+bj$, here$a=6\&b=2$
$$\begin{gathered} \parallel v\parallel =\sqrt{{\left(6\right)}^2+{\left(2\right)}^2} \\ \parallel v\parallel =\sqrt{36+4} \\ \parallel v\parallel =\sqrt{40} \\ \parallel v\parallel =6.324 \end{gathered}$$
