# If a point #P# has coordinates #(0,-2)# and #Q# is any point on the circle, #x^2+y^2 -5x-y+5=0#, then what is the maximum value of #(PQ)^2#?

##### 1 Answer

Answer is (2).

#### Explanation:

The center of the circle

Let us put the values of the corrdinates of

distance of

Distance of

and hence the maximum value of

=

=

Hence answer is (2).

graph{(x^2+(y+2)^2-0.01)(x^2+y^2-5x-y+5)=0 [-3.917, 6.083, -2.48, 2.52]}
