Question

1) Consider Fig. 12, which shows an infinite line of charge which contains a uniform charge of a coulombs in every meter. You will now use Gauss' Law to derive an equation for the electric field around a line of charge. Fig. 12 Describe the electric field in the region surrounding the charge. (Draw a few sample lines) Is this electric field symmetrical (spherically, cylindrically... Using this information, choose a notional surface enclosing one meter of the line of charge that allows you to easily compute the flux through it. What is the flux through the two ends of your notional surface? What is the area of the rest of your notional surface?

Elechic field due to infinite positively changed line is directed radially outward So the in the region surrounding wire the field is ontward. The electric field is symmetric and it follows cylindrical symmetry - d The notunal Cylindro surface is a cylinder of radu r and length L through two ends flux is zero because Ē is radially outwards & area verta is perpendicular it . for the rest of surface (curved sufaa) El da so coso = 1 O= o so lising Gauss law & Edă = q en now qenc = XL - E p da = XL dd = 21 IL to E Eo so E 42 IT VL) = a 1 hence E = a î 211 for
