NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 11
Assertion (A): The scalar product of two vectors is always a scalar quantity.
Reason (R): The dot product of two vectors A and B is given by A . B = A B cos θ, where θ is the angle between the vectors.
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 A
Detailed Explanation
The NCERT context explains that the dot product of two vectors results in a scalar, and the formula A . B = A B cos θ supports this by showing the product of magnitudes and a scalar (cos θ).
