Dear   arzoo

given tangent line and diameter line are parallel to each other

radius is equal to distance between ant tangent line and diameter line that is equal to = √2

and center of line lie on the line the diameter line/

let co ordinate of center is (h,k)

since this lie on line x-y=0

so h=k

so equation of circle  (x-h)2 +( y-h)2 =2

it is a family of circle one of the possible circle is for h=0

 x2 + y2 =2

similerly you will get many nore circle for different value of h

I think equation of diameter line should be x+y=0

then you will onle one circle  x2 + y2 =2
