NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 11
Assertion (A): The scalar product of two vectors is zero if they are perpendicular.
Reason (R): The scalar product is given as A . B = A B cos θ where θ is the angle between the vectors.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true, but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
The assertion is true as vectors are perpendicular when their scalar product is zero. The reason correctly explains that the scalar product formula includes cos θ, which becomes zero when θ is 90 degrees.
