When the gap is closed without placing any object in the screw gauge whose least count is 0.005 mm, the 5th division on its circular scale with the reference line on main scale. When a small sphere is placed, reading on main scale advances by 4 divisions, whereas circular scale reading advances to five times the corresponding reading when no object was placed. There are 200 divisions on the circular scale. The radius of the sphere is
