Let `A(bara)` and `B(barb)` be any two points in the space and `R(barr)` be a point on the line segment AB dividing it internally in the ration m : n the prove that `barr = (mbarb+ nbara)/(m+n)` . Hence find the position vector of R which divides the line segment joining the point A(1,-2,1) and B(1,4,-2) internally in the ratio 2: 1 .
