Step-by-step explanation:
Zero vector are those vectors whose norm is zero and whose direction and direction are undefined. However, they are vector, which posses zero length and no particular direction.
It is the vector of coordinates (0,0). Or, it is defined as the vector of length or zero modulus. The definition of a zero vector is a useful mathematical convention for solving vector equations. It plays the role of the neutral element for the addition of vectors. In a sense, it is an anomaly because it has no direction or meaning, but it is handy from the point of view of vector algebra.
From the question given :
The additive identity of the zero vector in the vector space can be written as:
