1.35 FIELD DUE TO AN INFINITELY LONG CHARGED WIRE uniform charge density of . wire having a uniform linear charge density . By symmetry, the field of the line charge is directed field due to an infinite plane sheet radially outwards and its magnitude is same at all Electric field due to a uniform points equidistant from the line charge. To determine plane sheet. As shown in Fig. 1. the field at a distance from the line charge, we choose infinite plane sheet of charge w a cylindrical Gaussian surface of radius , length and charge density . We wish to calcl with its axis along the line charge. As shown in Fig. at a point at distance from it. 1.97, it has curved surface and flat circular ends and the curved surface contributes towards the total flux. (a) Fig. 1.98 Gaussian surface charged infinite plane By symmetry, electric field normal to the sheet. Also, it mu tude and opposite direction at equidistant from the sheet and o choose cylindrical Gaussian surf. area and length with its axis (b) sheet. Fig. (a) Cylindrical Gaussian surface for line charge. As the lines of force are surface of the cylinder, the flux According to Gauss's theore area of the curved surface or Charge enclosed by the Gaussian surface, Using Gauss's theorem, , we get or or or Vectorially, Thus the electric field of a line charge is inversely proportional to the distance from the line charge. Figure shows where is the unit vector nor the variation of with distance from the line charge. going away from it.
