If two vectors `vec a and vec b` such that `|vec a|=2, |vec b|= 3 and vec a.vec b = 4`, find `|vec a - vec b|`

If two vectors vec(a) and vec(b) such that |vec(a)| = 2|vec(b)| = 3 and vec(a).vec(b) = 6 , find |vec(a)-vec(b)| .

If |vec a| = 2, |vec b| = 5 and |vec a xx vec b| = 8 then vec a . vec b

The vec a, vec b, vec c are three vectors which are respectively perpendicular to vec b + vec c, vec c + vec a and vec a + vec b , such that |vec a| =3, |vec b| = 4, |vec c| = 5 , then |vec a + vec b + vec c|=

If vec a and vec b are unit vectors such that |vec a xx vec b| = vec a . vec b , then |vec a + vec b|^(2) =

Let the vectors vec a and vec b be such that |vec a| = 3 and |vec b| = sqrt2/3 , then vec a xx vec b is a unit vector, if the angle between vec a and vec b is

If vec a and vec b are unit vectors such that |vec a + vec b| =1, then |vec a - vec b| =

Angle between the vectors vec a and vec b , where vec a, vec b and vec c are unit vectors satisfying vec a + vec b + sqrt3 vec c = vec 0 is

If vec a, vec b , and vec c are vectors such that |vec b| = |vec c| , then {[(vec a + vec b) xx (vec a + vec c)] xx (vec b xx vec c)} . (vec b + vec c) =
