Question

Non-zero vectors A and B are
perpendicular to each other, if
Select one:
a. AXB=0
b. AB=0
C.
d. JÄx|B=0​

Answer 1

Answer:

AB=0 this questions answered

Answer 2

Explanation:

$\huge\bf\blue{AnswEr\::-}$

Vector a is perpendicular to vector b if their dot product, a⋅b is 0 .

This is because a⋅b is defined as |a||b|cos(θ) where θ is the angle between a and b .

That is, it is the product of their magnitudes and the cosine of the angle between them. Of course, if the angle is 90∘ , then cos(90∘)=0and so a⋅b will be 0.

So, Opt. b will be your answer.
