Question
o illustrate the behavior of charge inside conductors, consider a long conducting rod that is suspended by insulating strings (see the figure). 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 applied to the rod and the surrounding region. The atoms in the rod are composed of positive nuclei (indicated by plus signs) and negative electrons (indicated by minus signs). Before application of the electric field, these atoms were distributed evenly throughout the rod. (Figure 1) Figure 1 of!Explanation / Answer
Part (A)
Electric field always directs from POSITIVE to NEGATIVE. Hence from the figure, we find out that Point A is positive and Point B is negative.
Now we know that a charge always attract towards opposite polarity. Hence, negatively charged electrons will experience an attraction force towards positive point A i.e. towards LEFT and positively charged nuclei will experience an attraction force towards negative point B i.e. towards RIGHT.
Option 2.
Part (B)
Due to attraction force electrons will move towards LEFT but nuclei, due to their mass will remain almost stationary.
Option 3.
