If M and N are two fixed points in a plane. Find the locus L = [P : PM = PN]
- A. a line equal to MN
- B. line parallel to MN
- C. Perpendicular bisector of MN
- D. A circle centre P, radius MN
Correct Answer: C. Perpendicular bisector of MN
Explanation
Locus L = (P : PM = Pn}
For M and N being two fixed points
Since PM = PN, P is equidistant from Mand N, So L must be the perpendicular bisector of the line MN
