The point dividing the line joining the points $ (1,2,3) $ and $ (3,-5,6) $ in the ratio $ 3:,5 $ is
Options:
A) $ ( 2,,\frac{-25}{2},,\frac{3}{2} ) $
B) $ ( -2,,\frac{25}{2},,\frac{-3}{2} ) $
C) $ ( 2,\frac{25}{2},,\frac{3}{2} ) $
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
$ x=\frac{-5+9}{-2}=-2,y=\frac{-5,(2)+3,(-5)}{-2}=-\frac{25}{2} $ $ z=\frac{-5,(3)+3,(6)}{-2}=-\frac{3}{2} $ .
