NEET Physics Scalar & Vector Products Assertion Reason Question
Assertion (A): The scalar product of two vectors can be zero even if neither of the vectors is zero.
Reason (R): If two vectors are perpendicular, their scalar product is zero.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
The scalar product is zero if the angle between the vectors is 90°, which means they are perpendicular, as stated in the reason.
