Question

A null vector has

• A. zero magnitude and a specific direction
• B. a finite magnitude and no specific direction
• C. a finite magnitude and a specific direction
• D. zero magnitude and no specific direction

Answer 1

The correct option is D zero magnitude and no specific direction

If vectors A and B are equal, i.e. A = B, then their difference (A – B) is defined as a null vector. It has a zero magnitude and no specific direction.
Hence the correct choice is (d).
