Question

The diagram show a locus P(x, y) which moves such that its distance from point M (0.h) is always equal. Given the equation of the locus of P is x2 + y2 – 10y = 0. Find the value of h.​

Answer 1

Answer:

Let the point be given by (h,k)

According to the given condition, 4∣k∣=h

2

+k

2

Replacing h by x and k by y, we get the required locus as x

2

+y

2

−4∣y∣=0
