Concept:When an object is placed at the centre of curvature of a concave mirror, the image formed is real, inverted, and of the same size as the object.
Explanation:The object is placed at the radius of curvature, which is the centre of curvature
C of the concave mirror.
For an object at
C, the image is formed at the same position
C.
The magnification produced by the mirror is
m=1.
Therefore, the image height equals the object height.
Given object height
=2.0 cm, the image height is also
2.0 cm.
Answer:D.
2.0 cm
