`BC` is divided into four equal parts by `P,Q` and `R`.The resultant of `vec(AB)` and `3vec(AC)` is A. `vec(AR)`B. `4vec(AR)`C. `4vec(AP)`D. `vec(PQ)` |
|
Answer» Correct Answer - B `vec(AC)+vec(CB)=vec(AB),vec(AC)+vec(4CR)=vec(AB)` `vec(AC)+vec4((AR)-vec(AC)),vec4(AR)-3vec(AC)=vec(AB)` `:.vec(AB)+3vec(AC)=4vec(AR)` |
