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(A)*vec(B)| ,then the angle between vec(A) and vec(B) will be

If |vec(a)xxvec(b)|=vec(a).vec(b), then angle between the vector vec(a)andvec(b) is ……………..

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

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

vec b,vec c are unit vectors and |vec a|=7vec a xx(vec b xxvec c)+vec b xx(vec c xxvec a)=(1)/(2)vec a then the angle between vec a and vec a is

If |vec a xxvec b|=|vec a*vec b|, then find angle between vec a and 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) .
