AP EAMCET · Maths · Circle
The polar of a point with respect to the circle \(x^2+y^2-\) \(10 x+12 y-3=0\) which is not a tangent and not a chord of contact is
- A \(2 x+3 y+8=0\)
- B \(3 x+4 y+5=0\)
- C \(5 x-12 y+7=0\)
- D \(6 x-8 y+15=0\)
Answer & Solution
Correct Answer
(D) \(6 x-8 y+15=0\)
Step-by-step Solution
Detailed explanation
Given equation of circle is \(x^2+y^2-10 x+12 y-3=0\) \(\therefore g=-5, f=6, c=-3\) centre \(=(5,-6)\) and \(r=8\) We know that that pole of polar \(A x+B y+C=0\) w.r to circle \(x^2+y^2+2 g x+2 f y+c=0\) can be find out by…
