Question

If A×B=B×A then angle between A and B is?

Answer 1

90° is the angle between them....I guess!!

Answer 2

Hi

Here is ur answer

A×B=B×A

A×B= − A×B

A×B=0

Therefore,

A=0 or B=0 or sinθ=0

If A or B are null vectors, then the angle between them is not defined.

If sinθ=0

Then,

θ=0,π(180 = π)

Hope it helps U
