Litu is trying to balance one egg on another egg, which rests on a table. He does it by taking an empty cylindrical plastic cup. The cup is inverted and put over the two eggs, so that the inner wall of the cup prevents the upper egg from falling down on the table.
Figure out the condition for the mass of the cup in terms of mass of eggs, radius of egg(assume eggs are spherical) and cup so that the cup tumbles over.
