A) \[(-5,2)\]
B) \[(2,-5)\]
C) \[(5,-2)\]
D) \[(-2,5)\]
Correct Answer: C
Solution :
\[\therefore \]Equation of required circle is \[{{(x-3)}^{2}}+{{y}^{2}}+\lambda y=0\] as, \[(1,\,\,-2)\] satisfy it, so \[\Rightarrow \,2(\sin \theta \,+\cos \theta )\,.(\sin \theta -\cos \theta )=0\] \[\therefore \]The equation of circle is \[{{x}^{2}}+{{y}^{2}}-6x+4y+9=0\] Clearly,\[(5,\,\,-~2)\] satisfy it.You need to login to perform this action.
