1. Figure 26.16 (p 721) Analyze the field lines and equipotential shells for the case where the left object is a planchette instead of a circle. Simplify the analysis by taking the planchette and bar as having equal surface area.

FIGURE 26.16 Estimating the field and potential between two charged conductors. The field lines are perpendicular to the equipotential surfaces. OV 50 V 10 V - - / 40 V 30 V 20 V The equipotential surfaces gradually change from the shape of one electrode to that of the other.STOP TO THINK 26.4 What total potential difference is created by these three batteries? 2 2.0 V + + 4.0V 6.0 V +
