Three vectors satisfyi the relation `vecA*vecB=0` and `vecA*vecC=0` then `vecA` is parallel to

A

`vecC`

B

`vecB`

C

`vecBxxvecC`

D

`vecB*vecC`

Text Solution

Verified by Experts

The correct Answer is:
C
`vecA*vecB=impliesvecAbotvecB`
`vecA*vecC=0impliesvecAbotvecC`
i.e., `vecA` is perpendicular to both `vecB and vecC`, i.e., `vecA` is parallel to `vecBxxvecC`.
