Let `vecA=3veci+4vecj`. Write four vector `vecB` such that `vecA !=vecB` but `A=B`.

Two vectors vecA and vecB are such that vecA+vecB=vecA-vecB . Then

Find |veca-vecb| , if two vectors vecaandvecb are such that |veca|=2,|vecb|=3andveca*vecb=4 .

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

What is the value of (vecA + vecB) * ( vecA xx vecB) ?

Given that vecA=vecB . What is the angle between (vecA+vecB) and (vecA-vecB) ?

The vector vecA and vecB are such that |vecA+vecB|=|vecA-vecB| . The angle between vectors vecA and vecB is -

If vectors vecA and vecB are such that |vecA+vecB|= |vecA|= |vecB| then |vecA-vecB| may be equated to

If vectors vecA and vecB are such that |vecA+vecB|= |vecA|= |vecB| then |vecA-vecB| may be equated to

If veca and vecb are two unit vectors such that veca+2vecb and 5veca-4vecb are perpendicular to each other, then the angle between veca and vecb is

vecA, vecB and vecC are vectors each having a unit magneitude. If vecA + vecB+vecC=0 , then vecA. vecB+vecB.vecC+ vecC.vecA will be:
