Electric Field due to a Hollow Cylinder of Charge

Electric Field due to a Hollow Cylinder of Charge



(a) Inside the cylinder (radial distance < R) :



When we draw a Gaussian cylinder of radius r, we find that the charge enclosed by it is zero.



This is possible if E = 0

(b) Outside the cylinder (radial distance > R) :





( qenc = λl)



Variation of E with r is also shown graphically here.
