University of Michigan Physics 340, Fall 2003 12 Sept. 2003 Reading: The problems here are based on material in French Chap.3 AND 4. The next 4 lectures will cover material through French Chap 4. A review of your old books and notes on LRC circuits might be good. Assignment 2: Oscillators, Damped Oscillators Due 9/24 in class, or in Amidei mailbox by 5pm. Problems: 1. French 3-4. Do not copy the answer from the book. Derive the answer. 2. A rod of mass M and length L hangs from an eyelet screwed in one end, and can swing like a pendulum. Find the frequency of this physical pendulum for small oscillations. 3. French 3-9. 4. Hydrogen chloride is an ionic molecule held together by the electrostatic attraction of H + and Cl - . Assume the heavier Cl is stationary and the H ion orbits around it at a radius r. The electrostatic potential energy of the system includes the Coulomb attraction, and also, at small r, a strong Coulomb repulsion between the positively charged nuclei. The repulsive term is found empirically to vary as r -9 . The total
