Question

Relative to an origin O, the position vector of A is -6i + 4j and the position vector of B is 18i + 6j. C lies on the y-axis and OC = OA + λOB.
Find OC.​

Answer 1

Answer:

Let the position vectors of two points A and B be aand b. OA = a ... respectively, with respect to a fixed origin O, where pand qare two non- parallel vectors. ... OA = a, OC = c ; OA = CB = a.
