If three vectors vecA, vecB and vecC satisfy the relation vecA.vecB = 0 & vecA.vecC = 0 then the vector vecA is parallel to vecB xx vecC . Statement-2 : vecA _|_vecB and vecA_|_vecC hence A is perpendicular to plane formed by vecB and vecC .

Assertion: If three vectors vecA,vecB and vecC satisfy the relation vecA.vecB=0 & vecA.veC=0 then the vector vecA may be parallel to vecBxxvecC .

Four vectors veca, vecb, vecc and vecx satisfy the relation (veca.vecx)vecb=vecc+vecx where vecb.veca ne 1 . The value of vecx in terms of veca, vecb and vecc is equal to

If veca, vecb, vecc are vectors such that veca.vecb=0 and veca + vecb = vecc then:

vecA, vecB and vecC are vectors such that vecC= vecA + vecB and vecC bot vecA and also C= A . Angle between vecA and vecB is :

Three vectors vecA,vecB and vecC are such that vecA=vecB+vecC and their magnitudes are in ratio 5:4:3 respectively. Find angle between vector vecA and vecC

If two out to the three vectors , veca, vecb , vecc are unit vectors such that veca + vecb + vecc =0 and 2(veca.vecb + vecb .vecc + vecc.veca) +3=0 then the length of the third vector is

The vectors veca and vecb are not perpendicular and vecac and vecd are two vectors satisfying : vecbxxvecc=vecbxxvecd and veca.vecd=0. Then the vecd is equal to (A) vecc+(veca.vecc)/(veca.vecb)vecb (B) vecb+(vecb.vecc)/(veca.vecb)vecc (C) vecc-(veca.vecc)/(veca.vecb)vecb (D) vecb-(vecb.vecc)/(veca.vecb)vecc

If three unit vectors veca, vecb and vecc " satisfy" veca+vecb+vecc= vec0 . Then find the angle between veca and vecb .
