What is the angle between overline A + overline B and overline A * overline B ? vectors ​

Answers 1

Answer:

Let R =A +B

P =A ×B

Now,

R ⋅P =A⋅P +B ⋅P

Because P  is the cross product, it is perpendicular to both A  and B.

R ⋅P =APcos90°+BPcos90°

R ⋅P =0

Therefore, R and P are perpendicular.

Thus the angle between them is  90°.
