The image formed by a concave mirror is observed to be virtual, erect and larger than the object. Where should be the position of the object?

(c) When object is placed between the focus and centre of curvature

(a) concave mirror (b) convex lens (c) concave lens (d) convex mirror

(b) virtual, behind the mirror and of the same size as the object.

The image formed by a concave mirror is virtual, erect and larger only when the object is placed between the pole of the mirror and its principal focus. So correct...

The virtual image formed by a concave mirror is always magnified whereas the virtual image formed by a convex mirror is diminished.

(c) both concave mirror and convex lens.

(b) concave lens provided the image is smaller than object. 

(a) Virtual image formed is larger in size in case of concave mirror.

(c) certainly real if the object is virtual

(c) The image of real object may be real in case of concave mirror
