NEET Physics Vectors MCQ Question
Which of the following statements about vectors is correct?
The sum of two equal vectors is always equal to zero.
Vectors can be added in any order due to the commutative property.
The magnitude of displacement is always greater than the path length.
Two vectors are equal if they have the same magnitude but different directions.
Correct Answer
Detailed Explanation
According to the NCERT context, vector addition obeys the commutative law, meaning the order of addition does not affect the result (A + B = B + A). Statement A is incorrect because the sum of two equal vectors is not zero but twice their magnitude. Statement C is incorrect as the magnitude of displacement is either less than or equal to the path length. Statement D is incorrect because two vectors must have the same magnitude and direction to be considered equal.
