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 positive
-axis, the angle is should be in second quadrant.
Substitute corresponding values in component form of vectors formula.
