Per NCERT §6.5, the vector product is which property algebraically?
AAnticommutative (A×B = −B×A)
BCommutative (A×B = B×A)
CDistributive but symmetric
DDistributive but commutative
Answer & Solution
Correct answer: A. Anticommutative (A×B = −B×A)
NCERT §6.5: A × B = −B × A. Distributive but not commutative.
