A small pin fixed on a table top is viewed from above from a distance of `50 cm`. By what distance would the pin appear to be raised, if it be viewed from the same point through a `15 cm`. Thick glass slab held parallel to the table? `mu` of glass is `1.5`. Does the answer depend on location of the slab ?
