. A tangent at a point on the circle x2 + y2 = a2 intcrsects a concentric circle
A tangent at a point on the circle x2 + y2 = a2 intcrsects a concentric circle at C at two points P and Q. The tangents to the circle X at P and Q meet at a point on the circle x2 + y2 = b2 then the equation cf circle is
(A) x2 + y2 = ab
(B) x2 + y2 = (a-b)2
(C) x2 + y2 = (a+b)2
(D) x2 + y2 = a2 + b2
Best Answer
Correct Answer:
(A) x2 + y2 = ab
