`vec(A)` and `vec(B)` are two Vectors and `theta` is the angle between them, if `|vec(A)xxvec(B)|= sqrt(3)(vec(A).vec(B))` the value of `theta` isA. `60^(@)`B. `45^(@)`C. `30^(@)`D. `90^(@)` |
Answer» Correct Answer - A `vec(A)xxvec(B)= AB sin theta` and `vec(A).vec(B)= AB cos theta` Given, `|vec(A)xxvec(B)|=sqrt(3)(vec(A).vec(B))` `implies AB sin theta= sqrt(3) AB cos theta` `implies tan theta= sqrt(3)` `theta= 60^(@)` |
