If vec a and vec b are unit Vectors, then what is the angle between vec a and vec b so that sqrt(2) vec a- vec b is a unit vector?

If vec a and vec b are unit vectors, then angle between vec a and vec b for sqrt(3)vec a - vec b to be unit vector is

If vec(a) and vec(b) are unit vectors, then the angle between vec(a) and vec(b) for sqrt( 3) vec( a) - vec(b) to be a unit vector is

If vec a and vec b are unit vectors find the angle between vec a+vec b and vec a-vec b

If vec a and vec b are unit vectors,and theta is the angle between them,then |vec a-vec b|=

If vec(a) and vec(b) are unit vectors, then find the angle between vec(a) and vec(b) , given that (sqrt(3)vec(a) - vec(b)) is a unit vector.

If vec a and vec b are unit vectors such that theta is the angle between then, |vec a - vec b| =
