A thin plano-convex lens is placed on a plane mirror as shown in the figure. The radius of curvature of curved surface is 40 cm. the refractive index of material of lens `n_(1)=1.5`. The refractive index surrounding is `n_(0)=1.2` An object O starts moving parallel to plane mirror. if final image of object moves with same speed as that of the object initially then distance of object O from the plane mirror is.
