The Paper Consists Of Molecules And In Each Of These The Charge May Not Be Uniformly Distributed A Simple Model For S 1 (147.68 KiB) Viewed 35 times

+ The paper consists of molecules and in each of these the charge may not be uniformly distributed. A simple model for such a molecule is illustrated in Fig. 1. Such a molecule is said to be polarized and is called an electric dipole. Figure 1: Electric dipole + c) Suppose that an electric dipole is placed near to another charged particle in the illustrated con- figuration. Draw the two force vectors, with the correct relative sizes, for the forces ex- erted on the charged particle by each end of the dipole. Explain what happens to the charged particle if it is initially at rest. d) Draw the force vectors for the forces exerted on the two ends of the electric dipole by the charged particle. Explain what happens to the electric dipole if it is initially at rest. Axle + e) Now consider a dipole which can pivot about a stationary axle through its center as illustrated below. Draw the force vectors, with the cor- rect relative sizes, for the forces exerted on the two ends of the electric dipole by the charged particle. Explain what happens to the electric dipole if it is initially at rest.
