A spherical surface of radius of curvature R, separates air (refractive index 1.0) fromglas (refractive index 1.5). The centre of curvature is in the glass. A point object P in air is found to have a real image Q in the glass.The line PQ cuts the surface at a point O and PO =OQ. The distance PO is equal to
