If vecA + vecB +vecC = 0 , then vecA xx ...

If `vecA + vecB +vecC = 0 `, then `vecA xx vecB ` is

A

`vecB xx vecC`

B

`vec C xx vec B`

C

`vec A xx vec C`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
`vecA + vecB +vecC=0 " or " vecA + vecC =- vecB`
`:. (vecA+vecC)xxvecB=-vecBxxvecB=0 " or " (vecAxx vecB)+(vecCxx vecB)=0`
or `vecAxx vecB =- vecC xx vecB " or " vecA xx vecB = vecBxxvecC`
