Let `vec a, vec b` and `vec c` be there unit vectors such that `vec a xx (vec b xx vec c)=(sqrt3)/2(vec b + vec c)`. If `vec b` is not parallel to `vec e`, then the angle between `vec a` & `vec b` is:

Let vec(a).vec(b) and vec(c) be three unit vectors such that vec(a) xx (vec(b) xx vec(c)) = (sqrt3)/(2) (vec(b) + vec(c)) . If vec(b) is not parallel to vec(c) , then the angle between vec(a) and vec(b) is

If vec a, vec b and vec c are non coplanar unit vectors such that vec a xx (vec b xx vec c) = (vec b + vec c)/sqrt2 , then

If vec a,vec b,vec c are three unit vectors such that vec a xx(vec b xxvec c)=(1)/(2)(vec b+vec c). If the vectors vec b and vec c are non-parallel,then the angle between vec a and vec b is

If vec a,vec b, and vec c are non-coplanar unit vectors such that vec a xx(vec b xxvec c)=(vec b+vec c)/(sqrt(2)),vec b and vec c are non parallel,then prove that the angel between vec a and vec b is 3 pi/4

Let vec(a),vec(b) and vec( c ) are three unit vectors such that vec(a)xx(vec(b)xx vec( c ))=(sqrt(3))/(2)(vec(b)+vec( c )) . If the vectors vec(b) and vec( c ) are not parallel then the angle between vec(a) and vec(b) is ……….

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) =

If vec a,vec b,vec c are 3 unit vectors such that vec a xx(vec b xxvec c)=(vec b)/(2) then (vec b and vec c being non parallel).(a)angle between vec a&vec b is (pi)/(3) (b)angle between vec a and vec c is (pi)/(3)( c)angle between vec a and vec b is (pi)/(2) (d)angle between vec a and vec c is (pi)/(2)

If vec a and vec b are unit vectors |vec a xx vec b| =1 then the angle between vec a and vec b is

Let vec a and vec b be two unit vectors such that |vec a+vec b|=sqrt(3) if vec c=vec a+2vec b+3(vec aXvec b) then 2|vec c| is equal to
