Which statement correctly compares the dot product and cross product?
ABoth are commutative
BDot product is a vector, while cross product is a scalar
CDot product is commutative, but cross product is anti-commutative
DCross product of parallel vectors is maximum
Answer & Solution
Correct answer: C. Dot product is commutative, but cross product is anti-commutative
The notes state that $\vec A\cdot\vec B = \vec B\cdot\vec A$, so the dot product is commutative. But $\vec A\times\vec B = -\vec B\times\vec A$, so the cross product is anti-commutative, not commutative. Parallel vectors have zero cross product.
