Question

A small object is kept in front of a convex refracting surface of refractive index 1.5 and radius of curvature 10 cm. If the real image is formed as far away from the centre of the surface as the object from it. Find the (i) Object distance (ii) nature and position of the image when the object is placed 15 cm in front of the refracting surface.
