Explanation:
We know that the given unit vector is in the direction of the x-axis.
Remember that an unit vector is a vector which magnitude is the unit, that's why is called like that.
So, the given unit vector can be written as
, where
indicates the horziontal coordinate and
indicates the vertical coordinate.
As a vertical or colum vector would be
![v=\left[\begin{array}{ccc}1i\\0j\end{array}\right]](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ckxbhzt72ykkur0t7h4cwzg4g5yqgjo3dk.png)
Therefore, the answer is
![v=\left[\begin{array}{ccc}1i\\0j\end{array}\right]](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ckxbhzt72ykkur0t7h4cwzg4g5yqgjo3dk.png)
