The angle between vectors `(vec(A)xxvec(B))` and `(vec(B)xxvec(A))` is

A

`pi//2`

B

`pi//3`

C

`pi`

D

`pi//4`

Text Solution

Verified by Experts

The correct Answer is:
C

We know that `vec(A)xxvec(B)= -(vec(B)xxvec(A))` because the angle between these two is always `90^(@)`
But if the angle between `vec(A)` and `vec(B)` is `0 or pi`. Then `vec(A)xxvec(B)= vec(B)xxvec(A)=0`
