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).vec(c )`D. `vec(b)xxvec(c )` |

Answer» Correct Answer - D `vec(a).vec(b)=0` i.e., `vec(a)` and `vec(b)` will be perpendicular to each other `vec(a).vec(c )=0 i.e., vec(a)` and `vec(c )` will be perpendicular to each other. `vec(b)xxvec(c )` will be a vector perpendicular to both `vec(b)` and `vec(c )` So `vec(a)` is parallel to `vec(b)xxvec(c )` |
