Given: two position vectors are


To find: position vector of the point which divided the join of points of given vectors in 2:1 externally


The formula used: The position vector of a point which divides the line of position vectors Y and X in the ratio m:n externally is given by,



Let the required position vector be


Here m = 2, n = 1,


Therefore,






Hence, the required position vector is
