A weightless rigid rod with a small iron bob at the end is hinged at point 
to the wall so that it can rotate in all directions. The rod is kept in the horizontal position by a vertical inextensible string of length 20 cm, fixed at its midpoint. The bob is displaced slightly perpendicular to the plane of the rod and string. Find period of small oscillations of the system in the form 
and fill the value of

The bob will execute SHM about the stationary axis passing through 
. If its effective length is
