The locus of the point of intersection of perpendicular tangents drawn to the circle x^2+y^2=10 is

Options

  1. Ax^2+y^2=5
  2. Bx^2+y^2=20
  3. Cx^2+y^2=25
  4. Dx^2+y^2=100

Correct answer

B. x^2+y^2=20

Step-by-step solution

Locus of points of intersection of perpendicular tangents is the director circle. Given circle is x^2+y^2=10 . Director circle is x^2+y^2=20 is the required locus.

A circle touches both the coordinate axes and the straight line L 4 x +3 y -6=0 in the first quadrant. If this circle lies below the line L =0 , then the equation of that circle is 2025If the smallest circle through the points of intersection of x^2+y^2=a^2 and x +y =p, 0 < p < a is x^2+y^2-a^2+ (x +y -p)=0 then = 2025If the lines 3 x-4 y+4=0 and 6 x-8 y-7=0 are the tangents to the same circle, then the area of that circle (in sq.units) is 2025Circles are drawn through the point (2,0) to cut intercepts of length 5 units on the X -axis.
