Total: 150

The time-period of a physical pendulum is 2π√I∕mgd, where I is the moment of inertia of the pendulum about the axis of rotation and d is perpendicular distance between the axis of rotation and the centre of mass of the pendulum. A circular ring hangs from a nail on a wall. The mass of the ring is 3kg and its radius is 20cm. If the ring is slightly displaced, the time of resulting oscillations will be

1.0s
1.3s
