A) \[1:2\] internally
B) \[1:2\] externally
C) \[-1:2\]
D) None of these
Correct Answer: B
Solution :
Let \[\lambda :1\] be the ratio in which ZX-plane divides the line segment AB. Day By section formula \[=\left( \frac{2\lambda +4}{\lambda +1},\frac{4\lambda +2}{\lambda +1},\frac{5\lambda +3}{\lambda +1} \right)\] For ZX-plane Cording of \[y=0\] \[\frac{4\lambda +2}{\lambda +1}=0\] \[\Rightarrow \] \[\lambda =-1/2\] \[\Rightarrow \] \[\lambda :1=-1:2\] Hence, ZX-plane i.e., point P divides the line segment AB in the ratio \[1:2\] externally.You need to login to perform this action.
