Object in diff orientations!

Consider a small object placed parallel to the axis of a transparent cylinder $(\mu = 1.5)$ as shown. The image is normal shifted towards observer by $\dfrac 2 3 \text{ m}$ . Now object is held perpendicular to axis as in figure $(ii)$ . Find the final location of image w.r.t. axis of cylinder (in $\text{m}$ ).

(Take appropriate assumption in first case).
