Intersection of two perpendicular tangents to the hyperbola \(\frac{x^2}{4}-\frac{y^2}{2}=1\) lies on the circle \(x^2+y^2=\ldots \ldots \ldots\)
  1. 2
  2. 12
  3. \(\sqrt{2}\)
  4. \(2 \sqrt{3}\)

Solution

Locus of point of intersection of perpendicular tangents to hyperbola \(\frac{x^2}{4}-\frac{y^2}{2}=1\) is the director circle \(x^2+y^2=4-2=2\) Hence, option (a) is correct.
