Answer 2

Given-

$9i-7j+13.9k$ vector is given

To Find-

The magnitude of the vector along the x-axis.

Solution-

To find the magnitude of any of the vectors along any direction the dot product can occur to fulfill the need

Here, the vector magnitude on the x-axis is

$9i-7j+13.9k$ dot product to the x-axis

So, ($9i-7j+13.9k$). (i)

Value is $9$.

Hence the magnitude of the provided vector in the direction of the x-axis is 9.
