The angle between the vector vec(A) and ...

The angle between the vector `vec(A)` and `vec(B)` is `theta`. Find the value of triple product `vec(A).(vec(B)xxvec(A))`.

Text Solution

Verified by Experts

Let `vec(A).(vec(B)xxvec(A))=vec(A).vec(C )`
Here `vec(C )=vec(B)xxvec(A)` which is perpendicular to both vector `vec(A)` and `vec(B)`
`:. vec(A).vec(C )=0`
