Let the angle between two nonzero vector `vecA and vecB` is `120^@` and its resultant be `vecC`.

Let the angle between two nonzero vectors vec(A) and vec(B) be 120^(@) and its resultant be vec(C) .

A class XII student appearing for a competitive examination was asked to attempt the following questions Let veca,vecb and vecc be three non zero vectors. Let veca,vecb and vecc be unit vectors such that veca.vecb=veca.vecc=0 and angle between vecb and vecc is pi/6 then veca=

Let veca and vecb be two orthogonal unit vectors and vecc is a vector such that vecc xx vecb = veca-vecc , then |vecc| is equal to

Let veca,vecb and vecc be three non-zero vectors such that no two of them are collinear and (vecaxxvecb)xxvecc=1/3|vecb||vecc|veca . If 'theta' is the angle between the vectors vecb and vecc , then a value of sin theta is :

vecA and vecB are two vectors of equal magnitude and theta is the angle between them.The angle between vecA or vecB with their resultant is
