pivot and masses 2.5 kg and 1 kg are suspended at
distances 40 cm and 100 cm respectively from the pivot as
shown. The rod is held at an angle ϴ with the horizontal
and released. Then
(a) the rod executes periodic motion about horizontal
position after the release
(b) the rod remains stationary after the release.
(c) the rod comes to rest in vertical position with 2.5 kg
mass at the lowest point
(d) the rod executes periodic motion about vertical
position after the release
