Calculate the electric potential at point P due to the point charge q=1.70 nC and the half-ring of charge (centered on P) with uniform density lambda=-10.6 nC/m. All dimensions are indicated in the figure. If you do not know how to calculate the field due to the half-ring, replace it by a point charge with the same total charge at end A of the ring.

Often we have distributions of charge for which integrating to find the electric field may not be possible in practice. In such cases, we may be able to get a good approximate solution by dividing the distribution into small but finite particles and taking the vector sum of the contributions of each. To see how this might work, consider a very thin rod of length -12 cm with uniform linear charge density λ=32.0 nC/m. Estimate the magnitude of the electric...
