A parallelogram OABC ,s.t a,b,c respectively are position vectors of A,B,C wrt O (origin).A poin P is taken on BC which divides it in ration 2:1.Also line segment AP intersects the line bisecting angle O internally in point Q.Also CQ whne extended meets AB in point R
Q1 Position vector of point Q
Q2 Vector AR ?
q3 Ratio in which R divides AB
Q4 RB=???
I have solved it....but need answers from u too ....to confirm..

1p.o.v of q=3/5(\vec{a}+\vec{c})
AR=1/3(\vec{b}-\vec{a})
AR:RB=1:2
RB=2/3(\vec{b}-\vec{c})
