Answer:
and
Step-by-step explanation:
The given sphere is
This can be rearranged as
On comparing with the standard equation of a circle , with center and radius .
The center of the given circle is .
Now, as the perpendicular distance, , of a point from a plane is
.
[ as the given plane is y=2]
Similarly, the other equation of the circle, can be rearranged as
Here, the center for this circle is
From the given condition, the distance of the center from the plane is .
[from equation (i) ]
and
and .
