(Ignore internal fields in the rod To understand how the charges within a conductor respond to an externally applied electric field, View Available Hint(s) To illustrate the behavior of charge inside conductors, consider a long conducting rod that is suspend insulating strings (see the figure). Assume that the rod is Both electrons and nuclei experience a force to the right. initially electrically neutral, and that it remains so for this discussion. The rod is positioned along the x axis, and The nuclei experience a force to the right and the electrons experience a force to the left. external electric field that poir (to the right) can be applied to the rod and the The electrons experience a force to the left but the nuclei experience no force surrounding region. The atoms in the rod are composed of positive nuclei (indicated by plus signs) and negative The electrons experience no force but the nuclei experience a force to the right. electrons (indicated by minus signs). of the electric field, these atoms throughout the rod. (Figure 1) Previous Answers Correct Part B What is the motion of the negative electrons and positive atomic nuclei used 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. Submit Previous Answers Correct The nuclei of the atoms of a conductin The motion of the electrons due to the e ctric field cons ged electrons are moving to the left, the current, Part Imagine that the rightward current flows in the rod for a a result, what will the net charge or View Available Hint(s) the right and left ends of the rod become? left end negative and right end positive left end negative and right end negative left end negative and right end nearly neutral left end nearly neutral and right end positive both ends nearly neutral Submit Part D Complete previous part(s) Provide Feedback Figure
