Three vectors vecA,vecB and vecC add up ...

Three vectors `vecA,vecB` and `vecC` add up to zero.Find which is false.

A

`(vecA xx vecB) xx vecC` is not zero unless `vecB, vecC` are parallel.

B

`(vecA xx vecB) * vecC` is not zero unless `vecB, vecC` are parallel.

C

If `vecA, vecB, vecC` define a plane, `(vecA xx vecB) xx vecC` is in that plane.

D

`(vecAxxvecB) * vecC = |vecA||vecB||vecC| toC^(2) = A^(2) + B^(2).`
