are any four vectors in 3 - dimensional space with the same initial point and such that 
show that terminals, A, B, C, D of these vectors are coplanar. Find the point at which AC and BD meet. Find the ratio in which P divides AC and BD.
respectively are such that 
. Show that the four points are coplanar. Also, find the position vector of the point of intersection of lines AC and BD.
Long Answer TypeShort Answer TypeWhen P lies outside AB and is nearer to A than B. then AP<PB.
Also division is external
∴ – 1 < λ < 0
When P is nearer to B than A, the AP > PB
∴ λ < – I
