(a) OM

(b)OL

(c) AL

(ii) Find the ratio AL :AN in its simplest form

4.

       
O is the origin and K is the point on AB so that AK : KB = 2 : 1.
OA = a and OB = b.
Find the position vector of K.
Give your answer in terms of a and b in its simplest form
5.


The diagram shows two points, P and Q, on a straight line AB.
P is the midpoint of AB and Q is the midpoint of PB.
