The wrong thing in Case I is that the rod is rotating around its side and not centre of mass -
Icm = ml2/12 and
Iaround side = ml2/3
it is rotating around O not c.o.m.
Got the mistake????

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
