If `veca=hati+hatj+hatk and vecb = hati-2hatj+hatk` then find vector `vecc` such that `veca.vecc = 2 and veca xx vecc = vecb`

Text Solution

Verified by Experts

`vecaxxvecb =veca xx (vecaxxvecc) = (veca .vecc)veca-(veca.veca)vecc= 2veca -3vecc`
`vecaxx vecb= |{:(pi,j,k),(1,1,1),(1,-2,1):}|=3hati-3hatk`
`vecc = 1/3 (2veca -vecaxxvecb) = 1/3 (-hati + 2hatj + 5hatk)`
