When vec(A)*vec(B)=-|vec(A)||vec(B)|, then

If |vec(A)+vec(B)|=|vec(A)|+|vec(B)|, then angle between vec(A)and vec(B) will be

Assertion : vec(A)xxvec(B) is perpendicular to both vec(A)+vec(B) as well as vec(A)-vec(B) . Reason: vec(A)+vec(B) as well as vec(A)-vec(B) lie in the plane contanining vec(A)and vec(B) , but vec(A)xxvec(B) lies perpendicular to the plane containing A and B.

If vec(A)xxvec(B)=vec(B)xxvec(A) , then the angle between vec(A) and vec(B) is-
