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 $\overrightarrow{A}=\overrightarrow{B}$, then their difference $\overrightarrow{A}-\overrightarrow{B}$ is defined as a null vector. It has a zero magnitude and no specific direction. Hence the correct choice is (d).
