A point object lies inside a transparent solid sphere of radius \( 20 \mathrm{~cm} \) and of refractive index \( n=2 \). When
\( \mathrm{P} \)
the object is viewed from air through the nearest
W
surface it is seen at a distance \( 5 \mathrm{~cm} \) from the surface. Find the distance of object when it is seen through the farthest curved surface.
