JEE Mains · Maths · STD 11 - 10.1 circle and system of circle

यदि किसी बिन्दु \(P\) के निर्देशांक \((0,-2)\) हैं तथा कोई बिन्दु \(Q\) वृत्त \(x^{2}+y^{2}-5 x-y+5=0\) पर स्थित है, तो \(( PQ )^{2}\) का अधिकतम मान है

  1. A \(\frac{{25 + \sqrt 6 }}{2}\)
  2. B \(14 + 5\sqrt 3 \)
  3. C \(\frac{{47 + 10\sqrt 6 }}{2}\)
  4. D \(8 + 5\sqrt 3 \)
Verified Solution

Answer & Solution

Correct Answer

(B) \(14 + 5\sqrt 3 \)

Step-by-step Solution

Detailed explanation

Given that \({x^2} + {y^2} - 5x - y + 5 = 0\) \( \Rightarrow {\left( {x - 5/2} \right)^2} - \frac{{25}}{4} + {\left( {y - 1/2} \right)^2} - 1/4 = 0\) \( \Rightarrow {\left( {x - 5/2} \right)^2} + \left( {y - 1/2} \right)3/2\) on circle…
