NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 11
Assertion (A): The scalar product of two vectors is a scalar quantity. | Reason (R): The scalar product of vectors follows the commutative law.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
Correct Answer
Option B
Detailed Explanation
The scalar product is a scalar as it results from A . B = A B cos θ, but the reason for it being scalar is not because it follows the commutative law. Commutativity is a property of the scalar product, not its explanation.
