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 two vectors is defined as the product of their magnitudes and the cosine of the angle between them.
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.
Correct Answer
Option A
Detailed Explanation
The scalar product or dot product of two vectors is indeed a scalar quantity, as it is defined as A . B = A B cos θ, which involves magnitudes of vectors and a scalar cosine term.
