HEY DEAR ...
If object is placed beyond the focus, then there may be three possibilities.
(a) Object is located between C and F
In this case, the image will be located beyond the center of curvature. Further, the image will be real and inverted. The size of the image will be greater than the size of the object.
(b) The object is placed at C
When the object is located at the center of curvature, the image will also be located at the center of curvature. In this case, the image will be real and inverted. The size of the image will be equal to the size of the object.
(c) The object is located beyond C
When the object is located at a location beyond the center of curvature, the image will always be located somewhere in between the center of curvature and the focal point. In this case, the image will be real and inverted.The size of the image will be less than the size of the object.
