A concave mirror, of aperture $4cm$, has a point object placed on its principal axis at a distance of $10cm$ from the mirror. The image, formed by the mirror, is not likely to be a sharp image. State the likely reason for the same.

Q. A $2.0cm$ long object is placed perpendicular to the principal axis of a concave mirror. The distance of the object from the mirror is $30cm$, and its image is formed $60cm$ from the mirror, on the same side of the mirror as the object. Find the height of the image formed :

Q. Object is placed on the principal axis of a concave mirror. Its real image is formed at a point which is 10 cm more distant from the mirror than the object. If focal length of mirror 12 cm. The magnification of the image is:
