If the coordinates of points P and Q are (3, 1, -2) and (1, -2, 2) respectively, then find the vector
The vector PQ is [(3-1) + (1-(-2) + (-2-2)
So,
What is the component of vector perpendicular to XY plane?
The component of vector is perpendicular in the XY plane in the Z direction.
So, it is
What is the direction of null vector?
Null vector cantake any arbitrary direction.
