In the figure shown `M_(1)` and `M_(2)` are two spherical mirrors of focal length `20 cm` each. `AB` and `CD` are their principal axes respectively which are separated by `1 cm. PQ` is an object of height `2 cm` and kept at distance `20 cm` from `M_(1)`. The separation between the mirrors is `50 cm` Consider two successive reflections first on `M_(1)` then on `M_(2)`. Find the size of the `2^(nd)` image. Also find distances of and points `P''` and `Q''` of that image from the line `AB`.
