Answer
Correct option is
B
Circle with out A and B
Given that A and B are two fixed points on a plane locus of P such that PA
2
+PB
2
=AB
2
, such that △PAB is a right-angled triangle.
Let the points A and B be and points of a diameter of circle C.
The locus of point P are the points comprising circle C,less points A and B.
∴ The locus of a point is a circle without A and B
