What is the force felt by the electrons and the nuclei in the rod when the external field described in the problem introduction is applied? (Ignore internal fields in the rod for the moment.) To illustrate the behavior of charge inside conductors, consider a long conducting rod that is suspended by insulating strings (see the figure). View Available Hint(s) Assume that the rod is initially electrically neutral, and that it remains so for this discussion. The rod is positioned along the x axis, and an external electric field that points in the positive x direction (to the right) can be Both electrons and nuclei experience a force to the right. applied to the rod and the surrounding region. The atoms in the rod are composed of positive nuclei (indicated by plus signs) and negative The nuclei experience a force to the right and the electrons experience a force to the left. electrons (indicated by minus signs). Before application of the electric field, these atoms were distributed evenly throughout the rod. (Figure_1) The electrons experience a force to the left but the nuclei experience no force. The electrons experience no force but the nuclei experience a force to the right. Submit Part B What is the motion of the negative electrons and positive atomic nuclei caused by the external field? View Available Hint(s) Both electrons and nuclei move to the right. The nuclei move to the right and the electrons move to the left through equal distances. The electrons move to the left and the nuclei are almost stationary The electrons are almost stationary and the nuclei move to the right.
