Question

The angle between( Ax B ) and (A+B) is:​

Answer 1

The vector given by (A⃗ × B⃗ ) is always perpendicular to both the vectors (given by the right hand thumb rule); making 90° with each

Now; (A⃗ +B⃗ ) is the resultant between two vectors which lies in the same plane of both A⃗ and B⃗

So (A⃗ × B⃗ ) is also perpendicular to (A⃗ + B⃗ )

ie; the angle between them is 90° too
