Answer

The vector whose magnitude (modulus) is zero, is called zero vector. Its direction is in definite. Those vector whose initial point and terminal point are one and the same, for example $\overrightarrow{ AA }, \overrightarrow{ BB }, \ldots$ etc. always express zero vector. It is shown by $\overrightarrow{0}$ or black zero $(\overrightarrow{0})$.
