Hey gys
Hence you have been told that the focal lenth of object 15 cm and it is placed 30cm from concave lens and its center of curvature = 2× focal lenth
= 2× 15 cm
= 30cm
It means that it is placed on centre of curvature therefore the image will also makeon center of curvature and other side of principle axis inherited and real image
