As the coordinates given are simple, we solve this in a simple way. Let D(a, b, c) be equidistant from O, A, B and C.
OD^2 = AD^2
a^2 + b^2 + c^2 = (a-2)^2 + b^2 + c^2
So a = 1.
OD^2 = BD^2
a^2 + b^2 + c^2 = a^2 + (b-2)^2 + c^2
So b = 1.
OD^2= CD^2 . So c = 1.
Answer: D(1, 1, 1). There is only one point.
Distance is sqrt(3).
