Under which of the following conditions a concave mirror
can form an image larger than the actual object?
(a) When the object is kept at distance equal to its radius of
curvature.
(b) When object is kept at a distance less than its focal
length.
(c) When object is placed between the focus and centre of
curvature.
(d) When object is kept at a distance greater than its radius
of curvature

Answer:
c) When object is placed between the focus and centre of
is your right answer
Answer:
(c) When object is placed between the focus and centre of
(c) When object is placed between the focus and centre of curvature.
Explanation:
When the object is located beyond radius of curvature(C), image is formed somewhere in between and C & F (focal point) and is inverted and smaller than the object.
When the object is kept at a distance equal to its radius of curvature, an inverted image is also formed at the radius of curvature and of equal length.
When the object is kept between focus and centre of curvature, a magnified inverted image is formed located beyond centre of curvature.
When the object is kept at a distance less than its focal length, an upright, magnified image is formed behind the mirror.
