Three vector `vec(A)`,`vec(B)`, `vec(C )` satisfy the relation `vec(A)*vec(B)=0`and `vec(A).vec(C )=0`. The vector `vec(A)` is parallel toA. `vec(B)`B. `vec(C )`C. `vec(B)xxvec(C )`D. `vec(B)xxvec(C )` |

Answer» Correct Answer - C If `vec(A).vec(B)=0,vec(A)` is perpendicular to `vec(B)`. If `vec(A).vec(C )=0,vec(A)` is perpendicular to `vec(C )`. So `vec(A)` is perpendicular to both `vec(B)` and `vec(C )`. Also `vec(B)xxvec(C )` is perpendicular to both `vec(B)` and `vec(C )`. Hence `vec(A)` is parallel to `vec(B)xxvec(C )` |
