Two plane mirrors $M_1$ and $M_2$ are placed parallel to each other $20 cm$ apart. A luminous point object $O$ is placed between them at $5 cm$ from $M_1$ as shown.

 

The distances (in cm) of three nearest images from mirror $M_2$ are $5,35,45$ respectively.

The distance (in cm) of three nearest images from mirror $M_2$ are $15,25,55$ respectively.

The distance (in cm) of three nearest images from mirror $M_1$ are $15,25,55$ respectively.

The distance (in cm) of three nearest images from mirror $M_1$ are $5,35,45$ respectively.
