Which of the following statement about the sum of the two vectors vecA " and " vecB , is/are correct ?

What is the property of two vectores vec A and vec B if: (A) |vecA + vecB|= |vecA - vecB| (b) vecA + vecB = vecA - vecB

If veca and vecb are two unit vectors such that veca+vecb is also a unit vector, then find the angle between vectors veca and vecb .

The resultant of two vectors vecA and vecb is perpendicular to the vector vecA and its magnitude is equal to half the magnitude of vector vecB . The angle between vecA and vecB is

Are the magnitudes of the two vectors (vecA-vecB) and (vecB-vecA) the same ?

Assertion: Vector addition of two vectors vedA and vecB is commutative. Reason: vecA+vecB=vecB+vecA

If veca and vecb are two vectors, such that veca.vecbgt0 and |veca.vecb|=|vecaxxvecb| then the angle between the vectors veca and vecb is

Statement I: If two vectors veca and vecb are such that |veca+vecb|=|veca-vecb| , then the angle between veca and vecb is 90^@ . Statement II: veca+vecb=vecb+veca .
