Question

if vector A is perpendicular to vector B then A.B =​

Answer 1

If two vectors a and b are perpendicular to each other, then which of the following holds true, A+B=0, A-B=0, A. ... A+B will, by force, result in a vector. Thus if is the result is and is not a scalar. Same for subtraction, which is just adding the negative directions, so those two are not going to apply.
