Q. 75.0( 3 Votes )

P and Q are two p

Answer :


Position vector (P.V) of P =

And Position vector (P.V) of Q =

By section formula we know that if a point(with PV R) divides a vector externally in the ration m:n

Then PV of R is given by:

As, a point R divides the line segment PQ in the ratio 2:1 externally.

m = 2 and n=1

P.V of R =

P.V of R =

P.V of R =
