A) \[a:b\]
B) \[b:c\]
C) \[c:a\]
D) \[c:b\]
Correct Answer: D
Solution :
Let the ratio be k : 1. Since on xy-plane z = 0 \[\Rightarrow \,\,\frac{-bk+c}{k+1}=0\,\,\Rightarrow \,\,k=\frac{c}{b}\]. Hence the ratio is c : b. Aliter : Using formula, required ratio is \[-\frac{c}{-b}=c\,\,:\,\,b.\]You need to login to perform this action.
