If the angel between unit vectors vec a and vec b60^(@) ,then find the value of |vec a-vec b|

Angle between vec(a) and vec(b) is 60^(@) then

Angle between vec(a) and vec(b) is 60^(@) then

Angle between vec(a) and vec(b) is 60^(@) then

The angle between vec(A) + vec(B) and vec(A) xx vec(B) is

What is the angle between A and the resultant of (vec A + vec B) and (vec A -vec B) ?

if vec a=2vec m+vec n,vec b=vec m-2vec n angle between the unit vector vec m&vec n is 60^(@).,a,b are sides of the parallelogram,then the length of the daigonals is:

If |vec a| = 4, |vec b| = 2, |vec c| = 6 and each of the angles between the vectors is 60^(o) then |vec a + vec b + vec c| =

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
