Let ABCD be square of side length 2 unit. C_(2) is the circle through verticles A,B,C,D and C_(1) is the circle touching all the sides of square ABCD. L is the line through A.A circle touches the line L and the circle C_(1) exrternally such that both the circles are on the same side of the line, then the locus of centre of the circle is |
