The equation of the circle which passes through the point \((3,2)\) bisects the circumference of the circle \(x^2+y^2=15\) and cuts the circle \(x^2+y^2+4 x+6 y+3=0\) orthogonally is

  1. A \(x^2+y^2+6 x+8 y-43=0\)
  2. B \(x^2+y^2+6 x-8 y-15=0\)
  3. C \(x^2+y^2-6 x+8 y-11=0\)
  4. D \(x^2+y^2-6 x-8 y+21=0\)

Answer & Solution

Correct Answer

(B) \(x^2+y^2+6 x-8 y-15=0\)

Step-by-step Solution

Detailed explanation

Let the equation of required circle is \[ x^2+y^2+2 g x+2 f y+c=0 \] Since, circle (i) passes through point \((3,2)\), so \[ \begin{aligned} & & 9+4+6 g+4 f+c & =0 \\ \Rightarrow & & 6 g+4 f+c+13 & =0 \end{aligned} \] Since, circle (i) bisects the circumference of the circle…
