Two vectors `vec(P) & vec(Q)` are arranged in such a way that they form adjacent sides of a parallelogram as shown in figure Which of the following options have correct relationshipA. `vec(Q)=vec(R)+vec(S)`B. `vec(R)=vec(P)+vec(Q)`C. `vec(R)=vec(P)+vec(S)`D. `vec(S)=vec(Q)-vec(P)` |

Answer» Correct Answer - B::D From parallelogram law of vector addition we know that (B) is correct `because" "vec(P)+vec(S)=vec(Q)` Hence `vec(S)=vec(Q)-vec(P)` |
