```										Dear Rishi Khare,
Ans:- On the  YZ plane the X co ordinate is 0. Hence,
let the ratio is p:1
hence the X co ord is=(3p+2)=0
So p= -2:3
Hence the point devides the line in the ratio of 2:3 EXTERNALLY.

Please feel free to post as many doubts on our discussion forum as you can. If you find any question Difficult to understand - post it here and we will get you the answer and detailed solution very quickly. We are all IITians and here to help you in your IIT JEE preparation.
All the best  Rishi Khare!!!
