can some1 tell me the solution of the following question (its in Oct/Nov 2010, 9709/32, Q7 Part(ii))
With respect to the origin O, the points A and B have position vectors given by
−−→
OA = i + 2j + 2k and
−−→
OB = 3i + 4j. The point P lies on the line AB and OP is perpendicular to AB.
(ii) Find the position vector of P.
