The radical axis of the co-axial system of circles with limiting points \((1,2)\) and \((-2,1)\) is
- A \(x+3 y=0\)
- B \(2 x+3 y=0\)
- C \(3 x+2 y=0\)
- D \(3 x+y=0\)
Answer & Solution
Correct Answer
(D) \(3 x+y=0\)
Step-by-step Solution
Detailed explanation
The radical axis of the co-axial system of circles with limiting points \(A(1,2)\) and \(B(-2,1)\) is the perpendicular bisector of line joining limiting points \(A\) and \(B\). \(\because\) Mid-point of \(A\) and \(B\) is \(\left(-\frac{1}{2}, \frac{3}{2}\right)\) and slope of…
