$\"\"$

The magnitude of vector $\"\"$ is $\"\"$ .

The vector $\"\"$ lies in $\"\"$ -plane.

The angle is $\"\"$ .

Component form of vector if the vector lies in $\"\"$ -plane : $\"\"$ .

Since the vector makes an angle left of the negative $\"\"$ -axis, the angle is considered to be in third quadrant.

Substitute corresponding values in component form of vectors formula.
