Here we will find what is the magnetic field inside a hollow cylindrical pipe. A very long charged solid cylinder of radius ' a ' contains a uniform charge density ρ. From the expression for E for this cylinder: E(r)=λr2πϵ0R2 for r≤R and E(r)=λ2πϵ0r for r≥R, find the expressions for the electric potential V as a function of r, both inside and outside the cylinder. If you stack these hollow cylinders, you end up with the part of the original cylinder that can be neglected. Magnetic field inside the hollow cylinder will be zero at any point. (a) Derive the expression for the electric field inside the volume at a distance r from the axis of the cylinder in terms of the charge density p. This can be proved by Gauss law. as electric field inside conductor is $0$, your question states a cylinder made of conducting material Moreover, would the electric field inside the cylinder be 0 because of the symmetry and since all electric field vectors that are exerted by each charge would cancel each other out? homework-and-exercises Sep 14, 2020 · In this video you will know about complete derivation of Electric Field inside and outside the uniformly charged cylinder @Kamaldheeriya Maths easyThis is m Electric Field Inside a Solid Cylinder Understanding the electric field within a solid cylinder, especially when the charge density is nonuniform, can appear daunting.
