A spherical glass is attached to a rigid wall as shown in the figure. An observer located at point O is looking at a point A on the wall. The refractive index of the glass is 1.5 and that of air is 1.0. The distances are OA=8cm,XA=3cm. If the radius of curvature of spherical glass surface is R=5cm, then the apparent distance of A from observer O is
