If `veca=2i+j +3k,b=pi+j+qk` and `(vecbxveca)=0` then `(p, q)=`

If veca =2i +4j - 5k, vecb =i + j + k and vecc =j+2k . Find the unit vector in the opposite direction of veca+vecb+vecc

If veca = 2i+j-k, vecb =-i+2j-4k and vecc=i+j+k , then find (vecaxxvecb).(vecbxxvecc)

If veca=i-2j+3k , vecb=2i+3j-4k and vecc=i-3j+5k ,then check whether veca , vecb , vecc are coplanar.

Let veca = 2i + j+k, vecb = i+ 2j -k and a unit vector vecc be coplanar. If vecc is pependicular to veca . Then vecc is

Let veca = 2i + j+k, vecb = i+ 2j -k and a unit vector vecc be coplanar. If vecc is pependicular to veca . Then vecc is

Let veca = 2i + j+k, vecb = i+ 2j -k and a unit vector vecc be coplanar. If vecc is pependicular to veca . Then vecc is

Let veca = 2i + j+k, vecb = i+ 2j -k and a unit vector vecc be coplanar. If vecc is pependicular to veca .Find vecc .

Consider the vectors veca=2i+j+3k,vecb=i+4j-k Write a vector vecd such that the projection of veca on vecb

If vec(a)= 2vec(i) -vec(j) + 3vec(k), vec(b)= p vec(i) + vec(j) + q vec(k) and vec(b) xx vec(a) = vec(0) , then
