A) \[\left( \frac{b}{2a},\frac{q}{2p} \right)\]
B) \[\left( -\frac{b}{2a},-\frac{q}{2p} \right)\]
C) \[\left( \frac{b}{a},\frac{q}{p} \right)\]
D) None of these
Correct Answer: B
Solution :
\[{{x}_{1}}+{{x}_{2}}=-b/q\] and \[{{y}_{1}}+{{y}_{2}}=-q/p\] |
Center \[\left[ \frac{{{x}_{1}}+{{x}_{2}}}{2},\frac{{{y}_{1}}+{{y}_{2}}}{2} \right]=\left[ -\frac{b}{2a},\frac{-\,q}{2p} \right]\] |
[Hint: required equation is |
\[{{x}^{2}}+{{y}^{2}}+\frac{b}{a}x+\frac{q}{p}y+\frac{c}{a}+\frac{c}{p}=0\Rightarrow B\] |
