If $\vec{u}, \vec{v}$ Are Non-Zero Vectors With $|\vec{z} \cdot \vec{v}|=\mid \overrightarrow{k z}\|\| \vec{v} \|$

True/False

If $\vec{u}, \vec{v}$ are non-zero vectors with $|\vec{z} \cdot \vec{v}|=\mid \overrightarrow{k z}\|\| \vec{v} \|$ , then $\vec { u }$ is either parallel or anti-parallel to $\vec { v }$ .
