Mathematics · JEE | VECTOR ALGEBRA
हिन्दीGiven below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The vector product of two vectors is not commutative. Reason (R): For any two vectors \( \vec{a} \) and \( \vec{b} \), \( \vec{a} \times \vec{b} = -(\vec{b} \times \vec{a}) \). In the light of the above statements, choose the correct answer from the options given below:
View Answer & Solution
Correct answer · Option A
Both (A) and (R) are true and (R) is the correct explanation of (A).
Explanation
Vector product is anti-commutative because reversing the order introduces a negative sign, making (R) the direct mathematical justification for (A).
