यदि `|vec(A)xxvec(B)|=vec(A)*vec(B)` हो तो A व B के बीच कोण है

The value of (vec(A)+vec(B)).(vec(A)xxvec(B)) is :-

The value of (vec(A)+vec(B)).(vec(A)xxvec(B)) is :-

The value of (vec(A)+vec(B)).(vec(A)xxvec(B)) is :-

Assertion: If theta be the angle between vec(A) and vec(B) , then tan theta= (vec(A)xxvec(B))/(vec(A).vec(B)) Reason: vec(A)xxvec(B) is perpendicualr to vec(A).vec(B) .

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

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

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

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