Where should an object be placed in front of a convex lens so as to obtain its real, inverted and magnified image?
To obtain a real, inverted, and magnified image of an object, it should be placed between the focus $F'$, and the centre of curvature $2F'$ of a convex lens.
Explanation
When an object is placed between $F'$ and $2F'$, means the object is at a distance greater than the focal length $f$ and less than twice the focal length $2f$, then the image formed is real, inverted, larger than the object (or magnified), and beyond the $2F$ on the other side of the lens.
