Answer
The vector whose magnitude is 0 is said to be a zero vector.
Work Step by Step
Consider the zero vector $0=0\mathbf{i}+0\mathbf{j}$.
The vector whose magnitude is 0 is said to be a zero vector.
It is represented as $0=0\mathbf{i}+0\mathbf{j}$.
The zero vector is also known as a null vector. It has no direction.
