In order to obtain a magnification of,- 0.9 (minus 0.9) with a concave mirror, the object must be placed:

A concave mirror produces a magnification of + 3. The object is placed:

If a magnification of, -2.5 (minus two point one) is to be obtained by using a converging mirror, then the object has to be placed:

An object is placed at a large distance in front of a concave mirror of radius of curvature 60 cm. The image will be formed in front of the mirror at a distance of :

In order to obtain a magnification of, -1.5 with a concave mirror of focal length 20 cm, the object will have to be placed at a distance :
