A 1.90 × 102-kg sculpture hangs from a horizontal rod that serves as a pivot about which the sculpture can oscillate. The sculpture\'s moment of inertia with respect to the pivot is 17.1 kg·m2, and when it is swung at small amplitudes, it is found to oscillate at a frequency of 0.874 Hz. How far is the pivot from the sculpture\'s center of mass?
Objects A and B are both positively charged. Both have a mass of 400g , but A has twice the charge of B. When A and B are placed 25cm apart, B experiences an electric force of 0.54N . What is the charge on A? If the objects are released, what is t..
