Consider the object shown in the figure. It consist of a solid hemisphere of mass M and radius R. There is a solid rod welded at its centre. The object is placed on a flat surface so that the rod isvertical. Mass of the rod per unit length is (M)/(2R). What is the maximum length of the rod that can be welded so that the object can performoscillations about the position shown in diagram? Note : Centre of mass of a solid hemisphere is ata distance of (3R)/(8) from its base.

1.	Consider the object shown in the figure. It consist of a solid hemisphere of mass M and radius R. There is a solid rod welded at its centre. The object is placed on a flat surface so that the rod isvertical. Mass of the rod per unit length is (M)/(2R). What is the maximum length of the rod that can be welded so that the object can performoscillations about the position shown in diagram? Note : Centre of mass of a solid hemisphere is ata distance of (3R)/(8) from its base.
Answer» ANSWER :Less than `SQRT((3)/(2))R`
