उत्तर
If the magnification has a plus sign, then image is virtual and erect.
Explanation:
A plus sign (+) in magnification means the image height (h') is positive, indicating it is formed above the principal axis. In optics, any image formed above the axis is always erect (upright). Erect images formed by spherical mirrors are always virtual, as they are created by the apparent intersection of light rays behind the mirror.
