Orthogonal Vectors and Dot Product
3/8
Two vectors are orthogonal. What is their dot product?
A
One, because orthogonal vectors are normalized to unit length by definition
B
Equal to the product of their norms, because orthogonality maximizes their alignment
C
Zero, because orthogonal vectors are perpendicular and cos(90°) = 0
D
Negative one, because orthogonal vectors point in opposite directions in the vector space
