A glass sphere has radius R=5.0cm and index of refraction n=1.6. paperweight is constructed by slicing through the sphere along plane that is 2.0 cm from the center of the original sphere,leaving a hemisphere with a height of h=3.0 cm. The paperweight is placed on a table and viewed from directly above by an observer whose distance is d=8.0 cm above the table-top.When viewed through the paperweight, how far away does the tabletop appear to be to the observer?
