If `vecAxxvecB=0, ` can you say that `a. vecA=vecB, b. vecA!=vecB?`

Vectors vecA, vecB and vec C are such that vecA.vecB =0 and vecA. vecC = 0 . Then the vectors parallel to vec A

If veca,vecb,vecc are unit vectors such that veca+vecb+vecc=vec0 , find the value of veca*vecb+vecb*vecc+vecc*veca .

If veca, vecb, vecc are unit vectors such that veca. vecb=0, (veca-vecc).(vecb+vecc)=0 and vecc=lambdaveca+muvecb+omega(veca xx vecb) , where lambda, mu, omega are scalars, then

If vecA, vecB, vecC are non-coplanar vectors then (vecA.vecBxxvecC)/(vecCxxvecA.vecB)+(vecB.vecAxxvecC)/(vecC.vecAxxvecB)=

If veca, vecb,vecc are unit vectors such that veca.vecb = 0= veca.vecc and the angle between vecb and vecc is pi//3 then the value of |vecaxxvecb -veca xx vecc| is

Vectors vecA and vecB satisfying the vector equation vecA+ vecB = veca, vecA xx vecB =vecb and vecA.veca=1 . Vectors and vecb are given vectosrs, are
