Question
If A.B is 1, then1 pointVectors A and B are perpendicularVectors A and B are parallelVectors A and B are anti-parallelNone of the above
Solution
The dot product of two vectors A and B is given by A.B = |A||B|cosθ, where θ is the angle between the vectors.
If A.B = 1, it means that the cosine of the angle between the vectors is 1 (since the magnitudes of the vectors cannot be zero).
The cosine of an angle is 1 only when the angle is 0 degrees.
Therefore, vectors A and B are parallel.
