The cross product ā × b̄ is:
AEqual to dot product
BAlways zero
CA scalar
DA vector perpendicular to BOTH ā and b̄
Answer & Solution
Correct answer: D. A vector perpendicular to BOTH ā and b̄
Cross product produces a vector perpendicular to BOTH input vectors, with magnitude |ā||b̄|sin θ. Direction by right-hand rule.
