Three Dimensional Geometry Question 311
Question: The co-ordinates of the point in which the line joining the points (3, 5, -7) and (-2, 1, 8) is intersected by the plane yz are given by
Options:
A) $ ( 0,\frac{13}{5},2 ) $
B) $ ( 0,-\frac{13}{5},-2 ) $
C) $ ( 0,-\frac{13}{5},\frac{2}{5} ) $
D) $ ( 0,\frac{13}{5},\frac{2}{5} ) $
Show Answer
Answer:
Correct Answer: A
Solution:
[a] Ratio $ =-( \frac{3}{-2} )=\frac{3}{2} $
$ \therefore $ Required co-ordinates of the points are, $ [ \frac{6-6}{5},\frac{10+3}{5},\frac{-14+24}{5} ]=( 0,\frac{13}{5},2 ). $
