8. (a) By Eq. 24-18, the change in potential is the negative of the “area” under the curve. Thus, using the area-of-a-triangle formula, we have VE d s x −= ⋅= = z 10 1 2 22 0 0 2 G G bg b g which yields V = 30 V. (b) For any region within 0 3 << − ⋅ z xE d s m, G G is positive, but for any region for which x > 3 m it is negative. Therefore, V = V max occurs at x = 3 m. d s x = z 10 1 2 32 0 0 3 G G which yields V max = 40 V.
