A line meets the coordinate axes at \(A\) and \(B\). If the perpendicular distances from \(A\) and \(B\) to the tangent drawn at the origin to the circumcircle of \(\triangle O A B\) are \(m\) and \(n\) respectively, then the diameter of that circle Is

  1. A \(\frac{m+n}{2}\)
  2. B \(\frac{3(m+n)}{4}\)
  3. C \(m+n\)
  4. D \(2(m+n)\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(m+n\)

Step-by-step Solution

Detailed explanation

Equation of circle passing through \((a, 0)(0, b)\) and \((0,0)\) is \(x^2+y^2-a x-b y=0\) Equation of tangent at origin, \(-a x-b y=0\)…
