QUESTION 2 Find the electric field everywhere of an infinite uniform line charge with total charge Q. Sol. Using Gauss's Law: DE dA = %3D EA = || E0 Since, its the line charge we use the area of a cylinder surrounding the line charge E*2 TT L= But all the charged get enclosed by the cylinder area, so denc = Q Deriving, we get: E = (1/2 TE0 )*(| IrL)
