If `vecA , vecB` and `vecC` are mutually perpendiculasr (no zero vectors) to each other, then choose the correct option.

A

`(vecA+vecB).vecC=AC+BC`

B

`vecA.(vecBxxvecC)=0`

C

`(vecAxxvecB).vecC = 0`

D

`vecAxx(vecBxxvecC)= 0`

Text Solution

Verified by Experts

The correct Answer is:
D
If `vecA , vecB` and …………..
`(vecAxxvecB)_|_ vecC implies (vecAxxvecB). vecC =0`
`(vecBxxvecC).11vecA implies vecA xx (vecB xxvecC) = 0`
