Total: 51

Two point-like objects of masses 20‌gm and 30‌gm are fixed at the two ends of a rigid massless rod of length 10‌cm. This system is suspended vertically from a rigid ceiling using a thin wire attached to its center of mass, as shown in the figure. The resulting torsional pendulum undergoes small oscillations. The torsional constant of the wire is 1.2×10−8Nmrad−1. The angular frequency of the oscillations in n×10−3‌rad‌ s−1. The value of n is________.
