Unformatted text preview: 51. The point at which we are evaluating the net field is denoted by P . The contributions to the net field caused by the two electrons nearest P (the two electrons on the side of the triangle shared by P ) are seen to cancel, so that we only need to compute the field (using Eq. 23-3) caused by the electron at the far corner, at a distance r = 0.17 m from P . Using 1/4πε0 = k , we obtain Enet = k e = 4.8 × 10−8 N/C . r2 ...
