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))`.

A

`A^(2) B`

B

Zero

C

`A^(2) B sin theta`

D

`A^(2) B cos theta`

Text Solution

Verified by Experts

The correct Answer is:
B
`(vec(B) xx vec(A)) is _|_^(ar) to vec(B)` as well as `vec(A)`.
`vec(A) . ( vec(B) xx vec(A)) = 0`
