alleryIf $\mathbf{A}\cdot\mathbf{B}=0$, then the vectors $\mathbf{A}$ and $\mathbf{B}$ are
Aparallel
Bequal in magnitude
Cperpendicular
Dcollinear
Answer & Solution
Correct answer: C. perpendicular
A zero dot product indicates orthogonality, so the vectors are perpendicular.
Parallel or collinear vectors generally have a nonzero dot product unless one vector is zero.
