Answer:
Parallel, since .
Step-by-step explanation:
The relation between both vectors is determined by the use of the dot product, whose expression is:
Where:
if vectors are parallel to each other and if vectors are orthogonal. Then, norms and dot product are calculated hereafter:
The two vectors are parallel to each other, which is also supported by the fact that one vector is multiply of the other one. That is,
