Solution

The correct option is C $π$
We know that , $\to A \times \to B = - (\to B \times \to A)$
But, if the angle between $\to A$ and $\to B$ is integer multiple of $π$ ,
Then only $\to A \times \to B = \to B \times \to A = 0$
Hence, the angle between $\to A$ and $\to B$ is $π$ according to options.

If →A and →B are two non-zero vectors and→A×→B=→B×→A then the angle between →A and →B is

The correct option is C πWe know that , →A×→B=−(→B×→A) But, if the angle between →A and →B is integer multiple of π, Then only →A×→B=→B×→A=0 Hence, the angle between →A and →B is π according to options.
