pendicular to A is given by
​

Answer 1

Answer:

Thank me an brainlist me

Explanation:

Moreover, the dot product of two parallel vectors is →A⋅→B=ABcos0°=AB A → · B ... When the vectors in (Figure) are given in their vector component forms, ... Since scalar products of two different unit vectors of axes give zero, and ... or antiparallel (ϕ=180°) ( ϕ = 180 ° ) because sin0°=sin180°=0 sin 0 ° = sin 180 ° = 0 .

Hope it helps!!!! : )
