If `vecAxxvecB=0, ` can you say that `a. vecA=vecB, b. vecA not equal to vecB?

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

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

Two vectors vecA" and "vecB have equal magnitudes. If magnitude of vecA+vecB is equal to n times the magnitude of vecA-vecB , then the angle between 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

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

If vecA xx vecB= vec0 and vecB xx vecC=vec0 , then the angle between vecA and vecC may be :

Three vectors veca,vecb and vecc satisfy the relation veca.vecb=0 and veca.vecc=0 . The vector veca is parallel to

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 |vecAxxvecB|=AB , then angle between vecA and vecB will be zero.
