From a point (1,0) on the circle x^2+y^2-2 x+2 y+1=0 if chords are drawn to this circle, then locus of the poles of these chords with respect the circle x^2+y^2=4 is

Options

  1. Ax=4
  2. Bx+2 y=5
  3. Cx^2+y^2-x-y=0
  4. D2 y^2=(x+1)

Correct answer

A. x=4

Step-by-step solution

Chord from point (1,0) on the circle x^2+y^2-2 x+2 y+1=0 is polar on the circle x^2+y^2=4 So, locus of poles of the chords is equation of polar at (1,0) on the circle x^2+y^2=4 i.e., x=4 .
