Type: MCQ-conceptual-Medium-Class 11
Which of the following statements about the scalar product of vectors is correct?
A
The scalar product is zero if the vectors are perpendicular.
B
The scalar product of two vectors is always greater than or equal to zero.
C
The scalar product depends only on the magnitudes of the vectors.
D
The scalar product is a vector quantity.
Correct Answer
Option A
Detailed Explanation
The scalar product (dot product) of two vectors A and B is zero if they are perpendicular, as indicated by the relationship A . B = |A||B|cosθ, where θ is 90 degrees in this case, leading to cos(90°) = 0.
