NEET Physics (general) MCQ Question
Which of the following statements about the scalar product of vectors is correct?
The scalar product of two vectors is a scalar quantity and follows the commutative law.
The scalar product of two vectors is a vector quantity and can be negative.
The scalar product depends only on the magnitudes of the vectors involved.
The scalar product is zero only when both vectors are equal in magnitude.
Correct Answer
Detailed Explanation
The scalar product of two vectors is indeed a scalar quantity and follows the commutative law, as stated in the NCERT context. Option B is incorrect because the scalar product is not a vector, C is incorrect because it also depends on the angle between the vectors, and D is incorrect as the scalar product can be zero if the vectors are perpendicular, not just equal.
