o -1 points Kat:PSE1 24 P 021 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 goed approximate solution by dividing the distribution into small but finite partices and taking the vector sum of the contributions of each. To see how this might work, consider a very thin rod of length 14 cm with uniform linear charge density λ-38.0...
