If ` vecalpha=3 vec i+4 vec j+5 vec k` and ` vecbeta=2 vec i+ vec j-4 vec k` , then express ` vecbeta` in the form of ` vecbeta= vecbeta_1+ vecbeta_2,` where ` vecbeta_1` is parallel to ` vecalpha` and ` vecbeta_2` is perpendicular to ` vecalpha` .

vec alpha=3hat i+4hat j+5hat k and vec beta=2hat i+hat j-4hat k then express vec beta in the form of vec beta=vec beta_(1)+vec beta_(2) where vec beta_(1) is parallel to vec alpha and vec beta_(2) is perpendicular to vec alpha .

If vec alpha=3hat i+4hat j+5hat k and vec beta=2hat i+hat j-4hat k then express vec beta in the form vec beta_(1)+vec beta_(2), where vec beta_(1) is parallel to vec alpha and vec beta is perpendicular to vec alpha.

If with reference to a right handed system of mutually perpendicular unit vectors hat i,hat j,hat k we have vec alpha=3hat i-hat j, and vec beta=2hat i+hat j-3hat k Express vec beta in the form vec beta=vec beta_(1)+vec beta_(2), where vec beta_(1) is parallel to vec alpha and vec beta_(2) is perpendicular to vec alpha .

| 2vec i-3vec j + vec k | =

(vec i + xvec j + 3vec k) xx (vec i-vec j + vec k) = 5vec i + xvec j-3vec k then x =

Let vecalpha = 3hati + hatj and beta= 2hati - hatj + 3hatk . If vecbeta = vecbeta_(1) - vecbeta_(2) , where vecbeta_(1) is parallel to vecalpha and vecbeta_(2) is perpendicular to vecalpha , then vecbeta_(1) xx vecbeta_(2) is equal to:

If vec a = 2vec i + 2vec j + vec kvec b = 5vec i + vec j + 2vec k then | vec a xxvec b | ^ (2) + (vec a * vec b) ^ (2) =

If a=vec i+4vec j,vec b=2vec i-3vec j and vec c=5vec i+9vec j then vec c=

If vec a xx i+2vec a-4vec i-2vec j+vec k=0 then vec a=
