A spherical surface of radius of curvature R separates air (refractive index 1.0) from glass (refractive index 1.5). The centre of curvature is in the glass. A point object P placed in air is found to have a real image Q in the glass. The lime PQ cuts the surface at the point O, and PO = OQ. The distance PO is equal to:
- (A):5R
- (B):3 R
- (C):2 R
- (D):1.5 R
