A uniform ring is rotating about vertical axis with angular velocity `omega` initially. A point insect (S) having the same mass as that of the ring starts walking from the lowest point `P_(1)` and finally reaches the point `P_(2)` (as shown in figure). The final angular velocity of the ring will be equal to

Text Solution
