A finite size object is placed normal to the principal axis at a distance of $\displaystyle 30$ cm from a convex mirror of focal length $\displaystyle 30$ cm. A plane mirror is now placed in such a way that the image produced by both the mirrors coincide with each other. The distance between the two mirrors is :
