Question
If 
an 
are position vectors of points A and B respectively, then find the position vector of points of trisection of AB.
Solution
Let P and Q be the points of trisection of AB. Then P divides AB in the ration 1 : 2 and Q divides AB in the ratio 2 : 1.
P.V. of P =
P.V. of Q =
P.V. of P =
P.V. of Q =
