If the angle between the vectors vec(A) ...

If the angle between the vectors `vec(A)` and `vec(B)` is `theta`, the value of the product `(vec(B)xxvec(A)).vec(A)` is equal to:

A

`BA^(2)sintheta`

B

`BA^(2)costheta`

C

`BA^(2)sinthetacostheta`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
D
Here `vec(c )=(vec(B)xxvec(A))=BAsintheta`then
`vec(c ).vec(A)=(Basintheta)Acos90^@`=zero
