is
Text Solution
Verified by ExpertsThe correct answer is:
B
First circle touches both axes and radius is 2 unit. Hence centre of circle is (2, 2).
Let radius of other circle be a and this circle also touches both the axes.
Hence centre of circle is ( a , a ).
This circle touches first circle
Hence,
squaring both the sides,



But
, Hence
is neglected
Hence,
.
