PROBLEM 3: An infinitely long cylinder of radius R has a volume charge density that varies with the radius as $\rho(r) = \rho_0(a-r)$ Where $\rho_0$ and a are positive constants and r is the distance from the axis of the cylinder. If the electric field on the surface of the cylinder is zero, what is a?

Step 1
The electric field is a vector quantity that represents the force experienced by a positive test charge placed at a given point. If the electric field is zero, it means that there is no force acting on the test charge at that point. In the case of a cylindrical Show more…

A very long cylinder of linear dielectric material is placed in an otherwise uniform electric field $\mathbf{E}_{0}$. Find the resulting field within the cylinder. (The radius is $a$, the susceptibility $\chi_{e},$ and the axis is perpendicular to $\mathbf{E}_{0} .$)
A very long cylinder, of radius $a$, carries a uniform polarization $\mathbf{P}$ perpendicular to its axis. Find the electric field inside the cylinder. Show that the field outside the cylinder can be expressed in the form $$\mathbf{E}(\mathbf{r})=\frac{a^{2}}{2 \epsilon_{0} s^{2}}[2(\mathbf{P} \cdot \hat{\mathbf{s}}) \hat{\mathbf{s}}-\mathbf{P}]$$ [Careful: I said "uniform," not "radial"!]
An infinitely long cylinder of radius R has a charge density ρ = ks^3. Find the electric field both inside the cylinder and outside the cylinder.
