Solution

OBJECT PLACED IN FRONT OF CONVEX MIRROR :

Place the object any where infront of convex mirror image formed is
(i) Between pole and focus ← position.
(ii) Diminished ← size.
(iii) Upright (erect) and virtual ← nature.
As the object is moved away from the mirror, the image shifts towards the focus and decreases in size but is (diminished).
