If `vecA+vecB+vecC=0` then show that `vecAxxvecB=vecBxxvecC=vecCxxvecA`.

Text Solution

Verified by Experts

`vecBxxvecC =vecBxx(-vecA-vecB)=-vecBxxvecA-vecBxxvecB=+vecAxxvecB-0=vecAxxvecB`
Now, `vecCxxvecA=(-vecAxx-vecB)xxvecA=-vecAxxvecA=vecBxxvecA=-0+vecAxxvecB=vecAxxvecB`
`therefore vecAxxvecB=vecBxxvecC=vecCxxvecA`
