QUESTION 4
Find the electric field everywhere of an infinite uniform line charge with total charge Q.
Sol.
Using Gauss's Law:
dA
EA =
Since, its the line charge we use the area of a cylinder surrounding the line charge
E*2T
L=
But all the charged get enclosed by the cylinder area, so
denc = Q
Deriving, we get:
E = (1/2 TE0 )*(
/rL)
