Question

8.
If A (1, 6) and B (3,5) are two points, then the
equation of the locus of point P (x, y) such that
segment AB subtends a right angle at P, is
A) x2 + y2 + 4x + 11y + 33 = 0
B) x2 + y2 - 4x – 11y + 33 = 0
O x2 + y2 + 4x - 11y + 33 = 0
D) x2 + y2 - 4x + 11y + 33 = 0​

Answer 1

Answer:

Let P(x, y) be any point on the required locus. ∴ ΔAPB is a right angled triangle. x2 + y2 – 4x – 11y + 33 = 0.
