Circles and having centres and respectively intersect each other at the points A and B. Secants and are drawn to the circles and to intersect them in the points and respectively. If the secants and intersect each other at a point P in the exterior region of circles and and , then which of the following statements is false

Options:

Answer:
D
Solution:

means P has equal powers with respect to both circles, so P lies on the radical axis, which is the line AB . So (A) is true. The line of centres is perpendicular to the radical axis, so (B) is true. The power of P with respect to is (the line PAB is a secant of ), so (C) is true. Nothing forces , so (D) is false.
