NEET Physics Scalar & Vector Products MCQ Question
Which of the following combinations about scalar and vector products is correct?
A scalar has direction; each component of a vector is a scalar; the total path length equals the displacement.
A scalar is a quantity with both magnitude and direction; the average speed can be less than average velocity.
Vectors can be added geometrically; the magnitude of a vector can change by multiplying with a negative number.
All scalar quantities are vectors; the direction of a unit vector is irrelevant to its magnitude.
Correct Answer
Detailed Explanation
Vectors can indeed be added geometrically, and multiplying a vector by a negative number reverses its direction while maintaining its magnitude. According to the NCERT context, a scalar has magnitude only, and unit vectors have a specific direction.
