If vecA xx vecB= vec0 and vecB xx vecC=v...

If `vecA xx vecB= vec0 and vecB xx vecC=vec0`, then the angle between `vecA and vecC` may be :

A

zero

B

`(pi)/(4)`

C

`(pi)/(2)`

D

None

Text Solution

Verified by Experts

The correct Answer is:
1
`vecA xx vecB = vec0 rArr vecA || vecB`
`vecB xx vecC = vec0 rArr vecB||vecC`
thus `vecA and vecC` may be parallel
