Answer» Solution :As shown in a thin straight INFINITELY long conducting wire having linear charge density `lambda ` is enclosed by a cylinder SURFACE of radius r and length l with its axis COINCIDING with the length of the wire. Asper Gauss.s law TOTAL ELECTRIC flux through the entire surface of the cylinder ` phi_in =(1)/(in_0) ` (charge enclosed within the cylinder) ` = (1)/(in_0)(lambda l)=(lambda l)/(in_0) ` ` (##U_LIK_SP_PHY_XII_C01_E09_022_S01.png" width="80%"> |
