Question: A physical pendulum performs small oscillations about the horizontal axis with frequency w1 = 15.0 S1. When a small body of mass m = 50

A physical pendulum performs small oscillations about the horizontal axis with frequency w1 = 15.0 S–1. When a small body of mass m = 50 g is fixed to the pendulum at a distance l = 20 cm below the axis, the oscillation frequency becomes equal to w2 = 10.0 s–1. Find the moment, of inertia of the pendulum relative to the oscillation axis.
