Uniformly charged insulating rods of length 14.0 cm (blue) and 7.0 cm (red) are bent into the shape of a semicircle as shown in Fig. 6. Longer rod has a total charge of -7 μC and shorter rod has a total charge of -3.5 µC. Find the electric potential at O, the center of both semicircles. Figure 6. Two charged semicircle rings.
