Solution

The correct option is B Aq, r; Bq, r; Cq, s; Dp, s
Convex mirror always produces virtual and diminished image of a real object.
Thus, m=+ve and m<1.
Real images are always inverted, hence m=ve
Virtual images are always erect, hence m=+ve
If images are enlarged then m>1 and if diminished then m<1.
For a concave mirror, a virtual and enlarged image will be formed for position of the object between Pole (P) and focus (F) and in all other cases a real and inverted image is formed.


Now,
(A) m=2, indicates an enlarged real image formed by a concave mirror.
(B) m=12, indicates a diminished real image produced by concave mirror.
(C) m=+2, indicates a virtual and enlarge image produced by concave mirror.
(D) m=+12, indicates a diminished virtual image produced by a convex mirror.
