if vectors `vecA = 2hati + 3hatj + 4hatk , vecB = hati + hatj + 5hatk and vecC` from a left - handed system, then `vecC` is

If vectors vecA=2hati+3hatj+4hatk, vecB=hati+hatj+5hatk and vecC form a left handed system then vecC is (A) 11hati-6hatj-hatk (B) -11hati+6hatj+hatk (C) -11hati+6hatj-hatk (D) -11hati+6hatj-hatk

If veca = 2hati -3hatj-1hatk and vecb =hati + 4hatj -2hatk " then " veca xx vecb is

If vectors veca =hati +2hatj -hatk, vecb = 2hati -hatj +hatk and vecc = lamdahati +hatj +2hatk are coplanar, then find the value of lamda .

Statement 1: vecA=2hati + 3hatj + 6hatk , vecB=hati + hatj - 2hatk and vecC=hati + 2hatj + hatk then |vecAxx (vecAxx(vecAxxvecB)).vecC|= 243 Statement 2: |vecAxx(vecAxx(vecAxxvecB)).vecC|=|vecA|^(2)|[vecA vecB vecC]|

If vectors veca =hati +2hatj -hatk, vecb = 2hati -hatj +hatk and vecc = lamdahati +hatj +2hatk are coplanar, then find the value of (lamda -4) .

The vectors are given below veca = hati + 2hatj +3hatk vecb = 2hati + 4hatj + 6hatk and vecc = 3hati + 6hatj + 9 hatk find the components of the vector veca + vecb -vecc

If veca=3hati+hatj-4hatk and vecb=6hati+5hatj-2hatk find |veca Xvecb|

Let veca= 2 hati + 3hatj - 6hatk, vecb = 2hati - 3hatj + 6hatk and vecc = -2 hati + 3hatj + 6hatk . Let veca_(1) be the projection of veca on vecb and veca_(2) be the projection of veca_(1) on vecc . Then veca_(1).vecb is equal to

Let veca= 2 hati + 3hatj - 6hatk, vecb = 2hati - 3hatj + 6hatk and vecc = -2 hati + 3hatj + 6hatk . Let veca_(1) be the projection of veca on vecb and veca_(2) be the projection of veca_(1) on vecc . Then veca_(2) is equal to

Find the sum of the vectors vec=hati-2hatj+hatk, vecb=-2hati+4 hatj+5hatk and vecc=hati-6hatj-7hatk
