Question

Vektor i adalah vektor satuan yang searah dengan sumbu X (dalam dimensi dua). Vektor jika dinyatakan dalam bentuk kolom adalah....

Answer 1

`v=\left[\begin{array}{ccc}1i\\0j\end{array}\right]`

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
`v=1i+oj`, where
`i` indicates the horziontal coordinate and
`j` indicates the vertical coordinate.

As a vertical or colum vector would be

`v=\left[\begin{array}{ccc}1i\\0j\end{array}\right]`

Therefore, the answer is

`v=\left[\begin{array}{ccc}1i\\0j\end{array}\right]`
